Detectives are appealing for information after an 18-year-old woman was raped on a student night out in Lancaster.
About 12.30am on October 1, the student was confronted by a man as she left a toilet cubicle in The Sugar House and pushed back inside the cubicle and raped.
She managed to fend off her attacker before running from the toilets to raise the alarm.
Detective Inspector Andy Hulme, from the Force Major Investigation Team, said: “This young woman has suffered a particularly distressing ordeal and she is being supported by specially trained officers at this time and we will continue to offer her support for as long as she needs it.
“There were around 1400 people at the club that night and we are appealing for anybody with any information about this incident to come forward.
“I specifically want to speak to any women who remember a man walking into the ladies’ toilets or who saw a man in there, or who heard any shouting.
“If any men were in the ladies’ loos for any accidental reason we would also like them to come forward so we can speak to them.” Call 101.
