A SEX offender from West Yorkshire at the centre of a nationwide manhunt is also wanted for murder
Detectives revealed that Peter McDonagh, 44, who has been missing from a hostel for two weeks is wanted by police over the murder of a prostitute eight years ago.
McDonagh was described as a danger to the public, particularly women, and may also endanger himself, officers added.
Police want to question him over the death of Michaela Hague, 25, who was killed in Sheffield in 2001.
McDonagh has been spotted in Manchester, Carlisle and Aberdeen since going missing on 11 February.
Police said that new evidence had come to light suggesting he might be linked to Ms Hague's death.
Det Supt Paul Taylor said: "We are obviously keen to trace Mr McDonagh, as we believe he may have vital information in respect of that murder inquiry."
McDonagh was jailed in 2002 for rape.
