A Labour Party official has resigned after being arrested on suspicion of "grooming" a schoolboy on the internet.
Peter Tuffley, 27, was arrested after a 13-year-old boy failed to return to his home in Bolton, Greater Manchester, on Saturday 12 March.
The teenager went home the following day but inquiries by police later revealed he had spent the night at a man's flat in Liverpool.
Mr Tuffley worked as a Labour Party regional organiser in Warrington.
He had previously worked in the Salford constituency office of Police Minister Hazel Blears.
Mr Tuffley was arrested on suspicion of grooming a child for sexual purposes. He was questioned and released on police bail until 4 May.
A Labour Party spokesman said: "We are aware of the allegations and the ongoing police investigation. "
"Mr Tuffley offered his resignation and we accepted it immediately. It would be inappropriate to comment further."
Mr Tuffley was unavailable for comment on Monday.
