BANGKOK: A gunman killed five security guards and wounded three other people in a mass shooting at a popular fresh food market in Thailand’s capital on Monday, police said.

The suspect opened fire with a “gun-type weapon” at the Or Tor Kor Market in Bangkok’s Bang Sue district at 12:31 pm (0531 GMT), police said, before taking his own life.

The shooting stemmed from a personal dispute, with the suspect — a former market employee — holding a long-running grudge against one of the security guards.

“We obtained this information from his wife’s testimony,” officer Sayam Boonsom told reporters at the scene.

Or Tor Kor Market is a short distance from Chatuchak market, a major tourist destination in Bangkok attracting throngs of visitors every weekend.

Mass shootings are not uncommon in Thailand, where firearms can be obtained relatively easily due to lax gun control enforcement.
