Three people are killed and 15 others injured in a knife attack in a supermarket in Shanghai

BEIJING – Three people were killed and 15 others injured in a knife attack at a supermarket in Shanghai, local police said.

A 37-year-old man surnamed Lin was arrested by police in response to a report of the attack on Monday evening, the local Songjiang Police Department said in a statement on Tuesday.

Eighteen people were taken to hospital for treatment, but three later died.

Police said Lin was having personal financial disputes and had come to Shanghai to “vent his anger” and that further investigations were underway.

The attack occurred in a suburb southwest of Shanghai and occurred on the eve of the week-long National Day holiday.

There have been several knife attacks in China this year.

Last month, a 10-year-old Japanese student died after being stabbed near his school in southern China. This follows another knife attack at a Japanese school bus stop in which a Chinese national who tried to stop the attacker was killed and a Japanese mother and her child were injured.

Earlier this year, a Chinese man stabbed four U.S. university lecturers and a Chinese man who tried to intervene in a public park in the northeastern city of Jilin. The four lecturers from Cornell College taught at Beihua University. Her injuries were not critical.
