A 50-year-old London man has died after a metal saw he was using to prune trees came into contact with a power line.

Fire officials say the man was trimming trees on private property at Avon Drive near Imperial Road (Highway 73) north of Aylmer, Ont. when the incident happened shortly after 3 p.m.

He was airlifted to hospital where he was pronounced dead.

The man was reportedly on an aluminum ladder, which was sitting on wet ground at the time, making the situation worse.

OPP say the man, identified as Janusz Danczak of London, was a friend of the property owner.

No foul play is suspected, but a post mortem examination has been scheduled for Tuesday.
