Nova Scotia's police watchdog is investigating the arrest of a man who suffered a broken elbow during a physical confrontation with an RCMP officer.

The Serious Incident Response Team said the Mounties responded to a complaint at about 1 p.m. on Thursday from a convenience store in Boylston about a man with a wooden club who had allegedly caused damage in the store and left with stolen property.

It said after the confrontation on the side of the road, the man was handcuffed and placed in a police vehicle.

He was later taken to St. Martha's Regional Hospital in Antigonish, where he was diagnosed with a fractured left elbow.

The Serious Incident Response Team investigates all serious incidents involving the police in the province, regardless of whether there is an allegation of wrongdoing.

The Police Act requires the team's director to file a public report summarizing the results of an investigation within three months of its completion.
