Five senior officers at Din Daeng police station were transferred and will be investigated following a 300,000-baht robbery at a gambling den in Bangkok early Wednesday morning.

Police said on Thursday that the Din Daeng station chief and four subordinates were transferred.

The gambling den was operating at an old snooker club on Pracha Songkhro 8 Road. The officers would be investigated to determine if they had been lax in enforcing the law against gambling.

A 22-second-long video posted in the Survive page in Facebook on Wednesday showed a man with what appears to be a gun scaring away people at a gambling table and snatching banknotes from boxes.

The man was wearing an orange cap, shorts and dark shirt and had a tattoo on his lower left arm.

The administrator of the Facebook page wrote that the incident happened early on Wednesday morning and identified the robber as “Mac Anusawaree”.

It was claimed the robber stole about 300,000 baht.

Police had yet to decide if they could take legal action because no one had filed a complaint about a robbery and police had yet to find out if the robber had a real gun.

The alleged robber turned himself in to police on Thursday afternoon after his mother was threatened.

Thanadisai Sompong, aka Mac Anusawaree, 36, told police at Din Daeng station that he robbed the gambling den because he had lost a lot of money there and had disputes with its guards for two days.

The Survive page on Facebook quoted the suspect as saying that he surrendered after about five men had tried to abduct his mother.

The suspect used an air gun during the crime and stole about 270,000 baht from the gambling den, the Survive page added.
