The inquiry into the disappearance of RAF gunner Corrie McKeague will be stood down and passed to a cold case team, police have confirmed, as the airman's father said he fears he might have killed himself.

Mr McKeague was 23 when he was last seen walking through Bury St Edmunds, Suffolk, in September 2016 after a night out with friends.

Police conducted two searches of a landfill site at Milton near Cambridge last year, with the first search lasting 20 weeks and the second, lasting seven weeks, concluding in December. No trace of Mr McKeague was found.

It is thought Mr McKeague might have climbed into a waste bin and was taken away by a bin lorry, prompting the landfill search.

Suffolk Constabulary said in a statement on Monday that investigators had been through all realistic possibilities in detail and that there was no evidence of foul play.
