Ottawa police are looking for three men after a sexual assault in downtown Ottawa early Saturday morning.

Police said a woman in her late teens was walking in the Byward Market when she was approached and sexually assaulted by an unknown man.

The suspect continued to follow the woman, according to police, until two other men intervened after hearing her ask for help.

The suspect then left the area.

He is described as being in his 20s, having light brown skin, around five feet seven inches tall, with a skinny build. He is English-speaking with an unknown accent.

Police said they’d also like to talk to the two men who intervened.

Anyone with information can call the Ottawa police’s sexual assault and child abuse unit at 613-236-1222 extension 5944, or Crime Stoppers at 613-233-08477.
