The father of Corrie McKeague has said his son is "no longer missing" as he claims he knows what happened to him and that he is in the waste disposal system.

The missing airman was 23 years old when he vanished on a night out in Bury St Edmunds, Suffolk, on September 24 2016.

Police believe he climbed into a waste bin and was taken away by a refuse lorry. He had been stationed at RAF Honington, around 10 miles from Bury St Edmunds.

No trace of him has been found, and police said in March that the investigation was being handed to a cold case squad.

Martin McKeague, Corrie's father, said on Facebook that he knows "what happened to our son", adding: "We are certain he is somewhere in the Suffolk waste disposal system, but his remains are essentially irretrievable."
