CCTV footage has been released of missing Scots airman Corrie McKeague a month after he went missing.

The video of the last confirmed sighting of the 23-year-old shows him in Brentgovel Street in Bury St Edmunds at 3.25am on Saturday, September 24. He had been at the club Flex with friends.

Suffolk Constabulary believe the RAF serviceman from Dunfermline may have later tried to walk the ten miles home to RAF Honington.

Officers coordinating the search hope the footage will jog people's memories of the night of Mr McKeague's disappearance.

Searches have been conducted this week in Great Livermere, with specialist RAF search officers joining police and Suffolk Lowland Search and Rescue volunteers to comb through woodland.

Earlier this week, Mr McKeague's mother Nicola Urquhart said there was no reasonable explanation for his disappearance.

She told Good Morning Britain: "There was nothing going on in his life. There was no major event, nothing that might cause him to suddenly think [of leaving] at 3am after he's had a drink, a week before pay day, when he's left his little seven-month old puppy in his room.

"He's been sending photos to friends, he's been in a fantastic mood."

Anyone who was in Bury St Edmunds, Honington or Barton Mills between 3am and 6am on the night Mr McKeague went missing is asked to call local police on 01473 782019.
