Toronto police have released a photo of two men suspected of sexually assaulting a woman in the stairwell of a downtown condominium in the Bathurst Street and King Street West area early Wednesday morning.

Police say a 19-year-old woman entered the elevator around 12:45 a.m. when two men entered behind her, pulled a gun on her and robbed her of her cellphone.

The woman was then "violently dragged" out of the elevator, according to police, and sexually assaulted in a stairwell nearby.

Both men then went to the underground parking garage and fled in a vehicle.

Police describe both men as in their early 20s, about 5'8'' to 5'10" in height with medium builds.

The first suspect was wearing a navy blue or black baseball cap with a white symbol on the front, black short-sleeve shirt with vertical white stripes, blue jeans and white Gucci brand sneakers and Gucci sunglasses.

The second suspect was wearing a brown and beige camouflage hooded sweat shirt, black baggy pants and dark-coloured shoes.

Police say the suspects fled in a grey- or silver-coloured four-door Mazda that had damage to the rear passenger side bumper that may have been secured with black tape.

Anyone with information is asked to contact police or Crime Stoppers.
