A 27-year-old Ottawa man faces various sexual assault charges after a police investigation into two incidents over the past two months.

In the first case, Ottawa police say Mohamad Kamel Sleiman posed as a police officer when he allegedly sexually assaulted a 15-year-old girl in January.

Police say the second incident involved inappropriate touching of an 18-year-old girl.

Sleiman is charged with sexual assault, sexual interference, invitation to sexual touching, impersonating a police officer and breach of recognizance.

He is scheduled to appear in court Monday.

Police ask anyone with information to contact the sexual assault and child abuse unit at 613-236-1222 ext. 5944 or Crime Stoppers at 613-233-TIPS.
