SYDNEY, N.S. -- The Cape Breton Regional Police Service has been cleared of any wrongdoing after a man died while in custody late last year.

The Serious Incident Response Team says it will not lay charges against any officers after a 66-year-old man who was arrested on Dec. 9 later died.

Police followed up on a tip about an SUV allegedly carrying marijuana that was about to board a ferry to Newfoundland.

Officers arrested a male driver who they took to jail.

The Serious Incident Response Team says the man was unresponsive when taken to the cell and despite efforts to revive him, he died.

The unit says he died as a result of a blockage in his coronary arteries, and while a search of his SUV found no drugs, it says the arrest and other actions of the police were appropriate.
