Incheon shopping complex stabbing injures at least eight as electronic monitoring comes under review

Attack followed a meeting with a probation officer

A 59-year-old man accused of stabbing shoppers at a commercial complex in Incheon had finished lunch with his probation officer just 70 minutes before the attack began, according to South Korea's Justice Ministry. The suspect was already wearing an electronic ankle monitor following a prison sentence for attempting to murder his former wife.

At least eight people were injured in the attack at about 1:40 p.m. on Tuesday, October 13, 2026, in a building housing the Homeplus Guwol supermarket in Namdong District. A woman in her 20s arrived at hospital in cardiac arrest and underwent emergency surgery. Business owners and shoppers used chairs to stop the attacker before police took him into custody.

Reports differ on the casualty total. A Korean account gives nine injured, while other accounts, including figures attributed to police and fire officials, give eight. The eight victims were described as six women and two men. There is no confirmed explanation for the difference.

Incheon Namdong Police Station was investigating the man on suspicion of attempted murder and other offenses. His name had not been released. Police were examining his movements through the building, substances found among his belongings and a possible connection to an earlier dispute at a hospital.

The Justice Ministry apologized and announced a review of both his supervision and the broader electronic monitoring system. Its account of counseling, a probation meeting and lunch on the morning of the attack places the timing of official contact at the center of that review.

What is known about the victims

Incheon's fire department said a woman in her 20s underwent surgery after arriving at a nearby hospital in cardiac arrest. Cardiac arrest means the heart has stopped pumping blood effectively. It is a medical emergency, but the description alone does not establish that a person has died.

No later outcome for the woman was given. The other victims were also taken to hospitals, but the fire department did not immediately provide detailed assessments of their injuries. Some reports described wounds to the back and shoulders.

One account listed the eight victims as two women in their 20s, a man in his 30s, four people in their 40s and a woman in her 50s. Those ages do not identify a ninth victim or resolve the conflicting totals. Headlines referring to one person in cardiac arrest and seven others injured describe eight casualties, not seven.

Authorities established an emergency medical center on the building's first floor to respond to additional casualties. The reports did not give a final update on how many victims remained hospitalized or how many required further surgery.

The route through the building is disputed

The attack unfolded across several levels of a complex containing a supermarket, dining areas and a cinema. Multiple accounts describe knives fastened to both of the suspect's hands and attacks while he moved along escalators.

Police accounts place part of the attack on an escalator between the second basement level, where Homeplus is located, and the second floor above ground. Other witness accounts say the violence began at a discount store in the basement before continuing upstairs.

A Korean account gives a different sequence: a woman in her 40s was injured on the ground floor, followed by seven people in the second floor food court and parking area, then a woman in her 50s on an escalator. It places a cinema on the third floor, while witness Nah Hyun-joon described the suspect heading toward a cinema on the fourth floor.

These differences leave the exact starting point and full route unresolved. Most accounts place the beginning at about 1:40 p.m. One report says the incident was reported at around 1:50 p.m., which may describe the reporting time rather than a different start time. Police had not publicly reconciled the floor descriptions.

Shoppers used chairs to stop the attacker

Nah Hyun-joon, a witness who helped restrain the suspect, described seeing him attack about four people in the second floor food court before moving to the third floor and stabbing at least one woman. Nah said several people then blocked the suspect's movement toward the cinema with chairs.

According to Nah, people above the suspect blocked the top of an escalator while others trapped him from below. They eventually pushed him down with chairs near the third floor escalator entrance and removed his knives before police arrived.

Nah described the attacker as silent and apparently striking people he encountered, rather than announcing a grievance or choosing victims in an obvious way.

He just went around stabbing people,” Nah said. “He didn’t even say anything. He just stabbed whoever he saw.

His account explains how civilians brought the attack to an end, but it does not establish the suspect's motive. Police were still investigating whether any victim had a connection to him. Another witness account said the knives were attached with tape and that additional knives were inside his bag. Those details require confirmation through the investigation.

A prior conviction and a recent hospital dispute

The suspect had been sentenced to four years in prison for attempted murder in 2015 and released in 2019. Reports identify the victim of that earlier attack as his former wife. After release, he was placed under electronic monitoring for a period extending into February 2029.

The Korean account gives the monitoring end date as February 23, 2029. Other accounts specify only February 2029 or the year 2029. The four years in prison and the decade of monitoring are separate periods, rather than evidence that he served a ten year prison sentence.

The Justice Ministry said the suspect had also been booked the previous month on suspicion of carrying a weapon during a protest outside an Incheon hospital. It described him using a kitchen knife to puncture a protest sign at a hospital where he had a dispute over medical treatment. Being booked means police opened a criminal case; it does not establish a conviction.

The ministry also said he had committed no repeat offenses while under supervision. That statement sits alongside the account of the recent weapon investigation. The distinction between a suspected offense under investigation and an established offense may matter, but the ministry's reported explanation did not resolve it. Police planned to examine whether the hospital dispute was connected to the shopping complex attack.

The morning's supervision timeline

The Justice Ministry provided unusually detailed times for the suspect's contact with officials that day. Its account says a probation officer confirmed that he had taken his medication and ate lunch with him before they parted.

• 2015: The suspect was sentenced to four years in prison for attempted murder.
• 2019: He was released and placed under electronic monitoring.
• The month before the attack: Police booked him over suspected weapon possession during a hospital protest.
• October 13, 10 a.m. to 11 a.m.: He attended a counseling session.
• 11:20 a.m. to 11:55 a.m.: He met his probation officer.
• Until 12:30 p.m.: The officer had lunch with him after confirming medication use.
• About 1:40 p.m.: The shopping complex attack began.
• February 2029: His electronic monitoring requirement was scheduled to end.

The interval from the end of lunch to the reported start of the attack was one hour and ten minutes. That calculation does not show what the officer could have predicted. It does identify a narrow period in which investigators will need to reconstruct the suspect's movements and determine when and how he obtained or prepared the weapons.

Medication and motive remain unresolved

Police said they found a large quantity of drugs among the suspect's possessions. He reportedly told investigators that he had taken drugs at the time of the attack. Police planned to submit the substances for analysis.

The substances had not been publicly identified. The term drugs in these accounts does not establish whether they were prescribed medicines, illegal substances or something else. The officer's confirmation of medication use earlier that day is also not proof of what the suspect took later or what effect it had.

The Justice Ministry said he was receiving treatment for alcohol dependence and unspecified mental illnesses. No diagnosis, clinical assessment or medical finding connecting those conditions to the attack was disclosed. His treatment history should therefore not be treated as an established explanation for the violence.

Police were considering the possibility of a planned crime, including the reported attachment of knives to his hands and the presence of additional weapons. Preparation, however, would not by itself explain why he attacked or whether he selected particular victims. Investigators had not publicly established a motive.

What the monitoring review will examine

South Korea's electronic monitoring program covers people convicted of offenses including murder and uses GPS to track their location in real time. A location signal can show where a person is; it does not directly reveal whether that person is carrying a weapon or intends to attack someone.

The Justice Ministry said authorities detected no attempt by the suspect to destroy his monitoring device. That makes the announced review broader than a question of whether the ankle monitor was physically working. It includes his supervision, the handling of recent warning information and the procedures surrounding electronic monitoring.

In its apology, the Justice Ministry acknowledged public concern about an attack involving someone already under supervision.

“We sincerely apologize over the great public concern caused by the knife attack by an individual under electronic monitoring,” the ministry said.

The ministry pledged to review the suspect's supervision and monitoring procedures more widely. It did not announce findings, identify a specific technical failure or give a date for completing the review. Whether the earlier hospital incident prompted changes to his supervision was also not publicly explained.

Police response and the wider safety context

Kim Jong-chul, acting chief of the National Police Agency, instructed police to conduct a swift and thorough investigation during a virtual meeting with police agency chiefs. He also ordered stronger prevention measures through sufficient police deployments in crowded public places.

Local police planned to seek a detention warrant after questioning the suspect. That would be a further judicial step beyond his arrest at the scene, not a finding of guilt. No hearing date or deadline for a charging decision was given.

The attack follows other episodes of violence against strangers in South Korea. A series of stabbing attacks in 2023 caused deaths, injuries and widespread fear. Reports also describe a fatal supermarket attack on a woman in her 60s in April 2025, and a May attack in Gwangju that killed a 17-year-old girl and injured another teenager. The man convicted in the Gwangju case received a life sentence.

Statistics Korea recorded about 0.5 homicides per 100,000 people in 2024, a figure described as roughly one tenth of the global average. That measure counts killings, not all assaults or attempted murders. It provides context for the country's low homicide rate without measuring the frequency of attacks like the one in Incheon.

The immediate priorities are more specific: establishing the final casualty total and victims' conditions, reconstructing the attack, identifying the substances found and determining whether supervision procedures failed to address a known risk. None of those questions had a final public answer.
