A DIVER who died while retrieving golf balls from a lake of a golf course in Co Antrim is understood to have been working with his son-in-law.
The man, who was in his fifties, died after diving with another man at Hilton Templepatrick on Tuesday afternoon.
It is understood the men ran a company, based in Co Antrim, which specialises in retrieving golf balls and selling them.
Police received a report shortly before 2.05pm on Tuesday that a man had got into difficulties in the lake.
It is understood a specialist police diving team recover the man's body five hours later.
It is believed that the man may have suffered a health complaint while in the water.
