Cape Breton Regional Police are investigating the death of a man in his cell at the Cape Breton Correctional Facility.

Chrissy Matheson of the Nova Scotia Department of Labour and Advanced Education says the man was found unconscious and unresponsive Sunday around 2:30 a.m.

Staff contacted emergency health services and immediately began medical treatment. The man was pronounced dead at 2:45 a.m.

"This is tragic news. My thoughts are with the family during this extremely difficult time," said Attorney General and Justice Minister Diana Whalen. "My department will be conducting an investigation."

Matheson says the man's next of kin have been notified and the body has been turned over to the medical examiner to determine the cause of death.
