Coast Guard divers retrieved the body of a man at Dean's Bay, Chaguaramas on Friday.
However, officers are uncertain whether it is one of the three fishermen who disappeared when their pirogue overturned in a boating accident in Los Iros, Erin, on Tuesday night.
It is also unlikely to be that of commercial diver Chevonne Bartholomew who disappeared off Chaguaramas on January 29 while working underwater.
Police said the body of an Indian male was spotted at around 8am.
The man is believed to be in his late 40s.
The body was handed over to officers of the Carenage Police Station.
Police are seeking the public's assistance in identifying the man.
