Ottawa police have laid more charges against a former teacher.
In June, Robert Clarke, 72, of Morrisburg, Ont.,
was charged with one count of sexual assault. At the time,
Ottawa police said they believed there could be more victims.
On Friday, Ottawa police said four more people have since come forward and Clarke is facing additional charges.
Clarke is now also facing four charges of gross indecency, two charges of sexual assault, and a charge of sexual exploitation.
He is scheduled to appear in court Aug. 22.
Ottawa police say the alleged incidents occurred between 1973 and 1992 while he was a teacher working for the Ottawa-Carleton District School Board.
The investigation is ongoing and police are concerned there could be more victims
