Police have released CCTV footage of the last confirmed sighting of an RAF serviceman who has been missing for almost a month.
Corrie McKeague, 23, vanished after going out for the evening with friends in Bury St Edmunds, Suffolk.
His mother Nicola Urquhart, of Dunfermline, fears a third party may have been involved but police said there is no evidence of criminality.
Suffolk Police has now released CCTV footage taken at 3.25am on Saturday, September 24 in a bid to find Mr McKeague.
The footage shows him in Brentgovel Street in Bury St Edmunds at the end of a night out when he was walking alone, eating fast food.
Police searches of woodland areas in the vicinity are continuing with the assistance of specialist RAF search officers, including around Great Livermere.
Officers had earlier searched a bin lorry, believing Mr McKeague’s mobile phone had been lost or discarded and ended up with the rubbish, but it could not be found.
Police also confirmed that a body found dumped in a Derbyshire layby was not that of Mr McKeague.
Mr McKeague, based at RAF Honington, Suffolk, is believed to have been wearing a pink Ralph Lauren polo shirt and brown suede Timberland boots at the time of his disappearance.
He is described as white, 5ft 10in and of medium build, with short light brown hair.
Anyone who may have been out in the Bury St Edmunds, Honington or Barton Mills area between 3am and 6am on Saturday, September 24 is asked to share information with police.
