The police are investigating the motive. So far it is a mass shooting, says Worapat Sukthai at the police in the Bang Sue district.
The perpetrator is said to have taken his life in connection with the incident. The police are working to identify him and "possible connections" to the border conflict between Thailand and Cambodia.
A video circulating on social media is said to show the shooter wearing a baseball cap and shorts when he enters the market with a backpack strapped to his chest and a pistol in his right hand.
The market is not far from the Chatuchak market, which is an important tourist destination in Bangkok.
