A 58-year-old Montreal man has been charged in relation to several historical sexual offences that happened at a campground in East Hawkesbury in the late 1990s.

Ontario Provincial Police said four young people, aged five to 12 at the time, were sexually assaulted on many occasions between 1995 and 1998.

The investigation led to the arrest of the accused, who police are not naming in order to protect the identity of the victims.

The accused faces 20 charges including several counts of sexual assault, sexual interference and sexual touching of a person under the age of 14.

He is scheduled to appear at the L'Orignal Court on Aug. 27.
