A HEADLESS corpse was found bobbing close to the reclaimed south-western coast of Singapore on Tuesday afternoon.

The left arm was also missing from the body, which is believed to have belonged to a dark-skinned man.

Police later fished out the body from the waters.

Thai workers digging up stones on the shoreline off Tuas South Avenue 1 made the grisly discovery at about 1.25pm.

One of them saw the body floating about two metres from a water breaker and alerted his boss, who called the police.

The body - clad only in blue jeans - is believed to have been decomposed for a few days, and could have floated in from Malaysian waters.

The head and the arm is believed to have been ripped off the body.

No identification documents were found.

The police has classified the find as an unnatural death case.
