Police have appealed for help in finding a convicted murderer who absconded from a prison in Lancashire.

Lester Jackson, who was convicted for murder following an incident in London in 1991, left HMP Kirkham on Monday to attend his work placement in St Annes.

The 43-year-old failed to turn up and has not been seen since.

Det Ch Insp Brian Quinn said he did not believe the public was at risk but "it is important he is returned to custody as soon as possible".

Jackson is described as white and around 6ft (1.82m) in height with a slim build, short brown hair and green eyes.

A police spokesman said the force had had to "check a variety of things" before making the appeal for help to the public.

Mr Quinn said that he could be in the St Annes or Blackpool area or possibly in Cumbria, Hertfordshire or London.

"I would appeal to anyone who knows where Lester Jackson is to come forward and contact the police immediately," he said.

"I would reassure the public that the relevant authorities carry out numerous checks on people prior to them being placed and that we have a team of officers searching for Jackson.

"At this stage, I do not believe that members of the public are at risk.
