A man found dead at the bottom of a Calgary manhole has been identified.

Mitchell David Forsyth, 25, of Calgary was found face down in about 15 centimetres of water in an Enmax electrical vault in the northeast community of Bridgeland on Wednesday. It took almost three hours for firefighters to recover his body.

Calgary police released the victim's name Friday, but said his cause of death is still under investigation.

Enmax, the city's electrical utility, said it appeared the man may have been electrocuted.

Pieces of copper wire were found around the open manhole, and tools were found in the vault where Forsyth's body was found.

The price of copper has tripled in the last five years, and metal recyclers in Calgary say they've seen an increasing number of people trying to sell stolen wiring.
