The body of a 58-year-old man, who has been identified as one Zainal Abidin Abdul Ghani, was found in Kallang River at about 8.10am on Friday morning.

A cleaner spotted the floating body in the river near Blk 3 Beach Road. The 58-year-old, who was wearing a grey shirt, was pronounced dead by paramedics at the scene.

Chinese evening newspaper Shin Min Daily News said the 70-year-old cleaner had been told by his boss to go check out the river, after someone told the boss that he saw a body in the river. The cleaner told his boss and called the police after confirming that there was really a body.

He told Shin Min: "When civil defence officers arrived, I saw them retrieving the body from the river with their bare hands. Last month, another old man also died in the river, and I didn't expect a similar case to happen today."

Police are investigating the case as an unnatural death.
