SINGAPORE - A kelong that drifted across the Johor Strait made its way to Sembawang Park on Tuesday (March 21) evening.

The Maritime and Port Authority of Singapore (MPA) said it received report of a floating structure adrift in East Johor Strait at 5.28pm.

"MPA immediately deployed patrol craft to investigate and monitor the structure," it said. "Concurrently, MPA issued navigation safety broadcast to warn traffic in the vicinity to keep clear of the structure. Traffic in the East Johor Strait was not affected."

At about 7.20pm, the structure beached at a rock bund near Sembawang Park and MPA port inspectors secured it to prevent it from drifting out again.

The structure appeared to be made of mainly zinc boards and there was a bed, utensils, a gas burner and clothes on it.

But no people were found on the structure, Shin Min Daily News said.

MPA said it is investigating the source of the structure and will be disposing it appropriately.
