The death of 51-year-old Arlon Fraser, of Rockly Vale, Scarborough, is currently under investigation, after his body was found floating in waters off Buccoo beach on Saturday night.
Fraser, an employee of the THA, went diving around 8 am Saturday at the beach and did not resurface.
Nine to ten hours later a lifeguard noticed a body floating in the water just off Buccoo beach and retrieved it.
The body was later identified as Fraser by his brother Colin Fraser and sister Claudette Fraser, both of Castara.
ACP William Nurse, in a newspaper interview, said that police prefer to wait for an autopsy before classifying it as a drowning.
