Three people were killed and 15 others injured in a stabbing at a Walmart supermarket in Shanghai's Songjiang district, police said. Officers arrested a 37-year-old suspect at the scene on Monday night, while the wounded were taken for medical treatment and investigators began examining the circumstances of the attack.
Police identified the detained man only by his surname, Lin. They said he had traveled to Shanghai and acted to vent anger arising from a personal economic dispute. That description was an initial police account, not a court finding, and the supplied evidence does not provide additional details about the dispute, the suspect's movements or whether he knew any of the victims.
The three people who died succumbed to their injuries in hospital. Police said the other 15 did not have life-threatening wounds and were not believed to be in danger. No names, ages or nationalities of the victims were included in the supplied report. Investigators said their work was continuing.
The attack occurred at Ludu International Commercial Plaza in Songjiang, a heavily populated area in southwestern Shanghai that also contains several universities. A jewelry shop operator in the mall told the BBC that people suddenly began running and that blood was visible. He said firefighters and armed police entered the complex and instructed people to evacuate. His account described panic inside the shopping center but did not establish the precise sequence of the attack.
The supermarket reopened on Tuesday with additional security. Online discussion of the incident appeared to have been restricted on Chinese social-media platforms, according to the BBC report. The evidence does not identify which posts or search terms were affected, so the extent and source of any moderation cannot be determined from the supplied material.
The stabbing occurred amid several other recent knife attacks in China, where civilian firearm ownership is prohibited. In September, a ten-year-old Japanese pupil died after being stabbed near his school in southern China. Four US college instructors were wounded in a park in Jilin in June, and an attack at a hospital in Yunnan in May killed two people and injured 21. Those incidents provide recent context but the evidence does not link them operationally or establish a shared motive.
For the Shanghai case, the confirmed public account remained narrow: a suspect was detained immediately, three victims died after reaching hospital and 15 others survived with injuries described as non-life-threatening. Claims about motive came from police at an early stage and would require further investigation and judicial proceedings before being treated as established fact.
