A woman's allegations that she was sexually assaulted after a man walked into an unlocked apartment in downtown Ottawa on Monday night are unfounded, police say.

The woman had told police it happened in an apartment in the Bronson Avenue and Gloucester Street area at about 11 p.m. Monday when the suspect walked through an unlocked door.

She claimed the suspect sexually assaulted her inside the apartment and later fled after confining her.

On Friday, two days after notifying the public about the alleged incident, police said the woman's allegations were unfounded and that the case is now closed with no charges being laid against either party.
