A WOMAN’S body has been found chained by the neck and tied underwater with two concrete dumbbells at a popular fishing pier in Thailand.

The horror discovery was made after stunned locals spotted the corpse floating close to shore.

The body was found on Friday near Ban Tha Yai pier in Phang Nga’s Mueang district.

Police Lieutenant Pheerawit Chaichanyut of Khok Kloi Police Station said officers rushed to the scene with Kusoltham Foundation rescue workers after receiving an emergency call.

The victim – whose identity, address, and nationality are still unknown – was wearing grey shorts and a brown round-neck T-shirt.

Police believe she had been dead for around two days before being found in the murky waters.

A heavy chain had been wrapped tightly around her neck and secured to two concrete dumbbells in what investigators believe was a calculated attempt to keep the body hidden on the seabed.

But despite the grim effort, currents carried her to the surface and she drifted close to land.

“This is a serious case, and we are treating it as a possible murder,” Pol. Lt. Pheerawit said.

“The way the body was weighted down points towards an attempt to conceal it.”

The body has been sent for a full autopsy to determine the cause of death and whether the woman was alive before entering the water.

Local leaders and neighbouring districts have been told to check missing persons reports for anyone matching her description.

Cops will meanwhile scour CCTV from the pier and surrounding waterways for suspicious movements in the days before the grim find.

Anyone with information – particularly those who may have noticed unusual activity near Ban Tha Yai pier – is urged to contact police immediately.

The case echoes a similar discovery in February when a fisherman in Rayong found a woman’s decomposed body inside a locked suitcase weighted with two 10kg dumbbells.

Her identity also remains unknown.

Elsewhere in Thailand, five people were gunned down in Bangkok in a market massacre allegedly sparked by a years-old grudge.

Police say the shooter – who later turned the gun on himself – opened fire near the busy Or Tor Kor market, killing four security guards and a vendor.

Two more people were wounded in the July 28 rampage.

Footage shows him in a black T-shirt, military-pattern shorts and a baseball cap, walking through a car park with a handgun after entering from the market gate.

“This is a serious case, and we are treating it as a possible murder,” Bangkok’s Metropolitan Police Commissioner said in a statement, adding that the alleged gunman’s wife claimed he had “a grudge against the security guards” after his car was scratched in 2019 or 2020.

His wife runs a food stall at the market, which sits next to the tourist hotspot Chatuchak weekend market.

Police say he was extremely protective of his car and had a history of violence.

Thailand has one of the highest levels of gun ownership in Asia, and while laws are restrictive, shootings remain relatively common.
