Police are hunting a man after he sexually assaulted a girl in Lancashire.
The 17-year-old victim is understood to have been attacked by the man after she met him on a night out on Saturday in Blackburn.
Lancashire Police said on Sunday the attack happened in the Richmond Terrace/King William Street area of the town.
A spokesman said officers were hoping to confirm what time the incident happened, in later interviews with the victim.
The teenager, who is not from Blackburn, told officers she had met the attacker while she was with a group of friends.
The man is described as Asian and between 5 ft 9 in and 5 ft 11 in tall.
He had pronounced overlapping teeth and a small, distinctive goatee beard. His hair was short at the sides and spiky on top.
Anyone with information about the attack should contact police in Blackburn.
