A man airlifted to hospital unconscious after the boat in which he was fishing capsized Tuesday has now died.

Nainaimo firefighters pulled two elderly men from the waters of  Westwood Lake  following the accident.

One of the men was airlifted to Victoria General Hospital unconscious. The second man was conscious when taken to Nanaimo General Hospital by ground ambulance.

Assistant Fire Chief Greg Norman says the pair's boat capsized around 3 p.m. PT. He says two members of the public were assisting the victims when firefighters arrived.

"One fellow was fishing on a pontoon boat and the other fellow was on the shore, and the guy in the pontoon boat was holding on to the one guy who was unconscious, keeping him up," said Norman," and then the other fellow swam from the shore and tried to do as much as he could."
