OPP in the Northern Bruce Peninsula are investigating after a 66-year-old man died while out diving at Fathom Five National Marine Park in Georgian Bay.

Investigators were called around 4 p.m. Tuesday for an investigation into the death of the Brampton, Ont. man.

Police say Andrew Liptak was one of five scuba divers on an expedition to the Caroline Rose Shipwreck in Driftwood Cove, but after entering the water showing no signs of distress, he was seen shortly afterward on the surface without vital signs.

Attempts were made to resuscitate him, but he was pronounced dead by the Coroner.

A post-mortem examination is expected to be conducted in London.
