A missing 17-year-old girl is believed to be with a wanted man who has a history of violence, police said.
Police think Chloe Campbell and Craig Moran, 32, both from Rochdale, may be in Blackpool after the pair were potentially spotted at the resort's Pleasure Beach and train station.
Moran has a history of violence and is wanted on a recall to prison for breaching the terms of his licence.
He is now also wanted on suspicion of child abduction due to Chloe's age, said Greater Manchester Police.
Chloe disappeared on Thursday September 7 and was last spotted in Rochdale with Moran two days later.
Detective Inspector Joanne Reid said: "We have genuine concerns for Chloe's safety, particularly whilst she is in the company of Moran. There is no suggestion that Chloe was forcibly taken, however we need to bring her home to ensure she is safe."
Chloe is described as white, approximately 5ft 3in and of slim build with long brown hair and blue eyes. She is known to wear a black leather-style jacket with fur around the collar, dark ripped jeans and tan ankle boots.
