Police in Sheffield are hunting for a convicted rapist who is believed to have travelled to the city after absconding from prison.
Neil Trennan, 60, was given day release from North Sea Camp, an open prison in Boston, Lincolnshire, on Thursday, but did not return to his meeting point.
Lincolnshire Police believe Trennan, who was last seen wearing a black t-shirt and grey bottoms, caught a Nottingham-bound train from Boston Train Station at about 10:49 BST.
Det Insp Dave Penney, from Lincolnshire Police, said Trennan was a “dangerous individual” who “may pose a real danger to members of the public”.
