Police in Thailand arrested a 14-year-old boy after a shooting at a luxury shopping mall in the capital Bangkok on Tuesday left at least two people dead and five others injured, causing terrified shoppers to flee the scene.

The shooting took place around 4:20 p.m. local time (5:20 a.m. ET), Police Lt. General Samran Nualma, assistant commissioner-general of the Royal Thai Police, said at a press conference Wednesday.

The suspect, who is reported to have mental health issues, was apprehended just under an hour after the shooting started and taken to a nearby hospital after being interrogated by police, Thai Police General Torsak Sukvimol told reporters.

One of the deceased victims is a Chinese citizen and the other a Myanmar national, Sukvimol said.

Three Thai citizens, one Chinese national and one Laos national were injured in the shooting with “varying degrees of severity,” Ministry of Foreign Affairs spokesperson Kanchana Patarachoke said Wednesday.
