A diver who died while fetching golf balls from a lake on a golf course in Co Antrim is believed to have worked with his son-in-law.

The man, who was in his fifties, died Tuesday afternoon after diving with another man at the Hilton Templepatrick.

The men are believed to be running a Co Antrim-based company that specializes in the retrieval and sale of golf balls.

The police received a message shortly before 2:05 p.m. on Tuesday that a man had got into trouble in the lake.

It is believed that a specialized police diving team can recover the man’s body five hours later.

It is believed that the man may have suffered health problems in the water.

Antrim and Newtownabbey City Council is investigating the man’s death.

A spokeswoman said yesterday, “Antrim and Newtownabbey Borough Council environmental protection officers are conducting an investigation under the Labor Protection Ordinance (Northern Ireland) 1978.

“As this is a live investigation, no further details can be given at this time.”

A spokesman for the health and safety committee said it was not involved in the investigation.
