SUDBURY -- Members of the Ontario Special Investigations Unit have been called to Espanola after a person was injured during an arrest Sunday evening.

It all started with a suspicious person complaint in the community during the dinner hour.

The Ontario Provincial Police's Manitoulin detachment was called and took the individual into custody, who later had to be treated at hospital for an injury.

OPP isn't releasing any other details as it's now before the SIU, the civilian law enforcement agency that looks into police actions after someone is seriously injured.
