A passer-by stopped a sex attacker in his tracks after shouting at him on a Brighton beach.
The attacker had dragged an 18-year-old girl on to the beach and was carrying out a serious sexual assault when he was interrupted.
The passer-by shouted “Hey! What’s going on?”
The victim, who had left the Coalition night club at about 4am on Sunday 13 March, struggled free and fled.
DC Jon Freeman, from Brighton CID, said: “The victim has only just reported the incident to police as she has tried to put the attack behind her.
“But this was a serious incident which understandably has left her very upset.
“We would like to hear from anyone who saw what happened or who has information about this assault, particularly the member of the public who shouted out while it was taking place, enabling the victim to break free.”
The victim described her attacker as either Arabic or Pakistani, with black short hair, aged between 20 and 30, about 5ft 5in to 5ft 7in tall and of proportionate build.
He was wearing a grey coloured V-neck jumper with a white top underneath, dark coloured jeans, rimless glasses and possibly light coloured trainers.
