Man pulled from water in Sydney's south

An elderly man pulled from the water at a south Sydney beach has died.

Emergency services were called to Lady Robinsons Beach, Brighton-Le-Sands about 4pm on Friday after reports a man had been removed from the water and was suffering a medical episode.

Footage from the Seven Network shows people surrounding the man, who police say is thought to be in his 70s, on the crowded beach.

The death is the third NSW water fatality within a day.

Two bodies, thought to belong to a 14-year-old boy and a 42-year-old man missing for days, were also found in different parts of the state on Friday.
