The Ottawa police sexual assault unit is now investigating alleged cases where five women were reportedly approached from behind by a man Saturday or Monday who attempted to pull their pants down.

Two incidents reportedly happened early Saturday morning between 6:00 a.m. and 7:15 a.m. in in the area of Albert Street between Bronson and Empress avenues.

In the first incident, a suspect followed a female on the street and pulled her pants down to her knees, inappropriately touching her in the process.

Three more similar incidents happened Monday between 6:20 a.m. and 6:45 a.m. at O'Connor Street and Lisgar Street, Preston Street at Saint Anthony Street and Loretta Street at Young Street.

The suspect in each instance is described as a white male with an average build, about five feet six inches tall, with short dark hair. His age is about 30 years old and he was wearing a dark or grey hoodie and either jeans or grey sweatpants.
