A 20-year-old female tourist was raped by a stranger on Blackpool seafront, police have said.
The incident was reported to have happened on Blackpool Promenade, near the Sea Life Centre, at 4.15am on August 19.
Police are trying to trace a group of people who approached the victim, who was visiting the resort from Sunderland, outside Coral Island at around 3.40am, 35 minutes before the alleged attack.

Police also want to speak to a taxi driver who took the woman to an address on Dean Street after 4.15am.

“If you saw this girl in the area of the Promenade around Coral Island or Madame Tussauds, please call us as soon as possible as you could have vital information to assist our investigation.”
