A teenage girl was waiting at a bus stop in northeast Calgary late Friday night when she was attacked by two strangers and taken to a home where she was sexually assaulted for hours before she managed to escape, police say.
The girl was taken to hospital after she suffered physically injuries, including a possible concussion; she has since been released.
Then Sunday morning, officers took three men into custody from the house described by the girl.
Two men in their 20s are considered suspects.
One of them is known to police.
A third man is being interviewed as a witness.
