Corrie McKeague went missing during a night out in Bury St Edmunds, Suffolk, on September 24, last year

Police are releasing pictures of people they believe were the last to see Corrie McKeague on the night he disappeared.

The RAF airman, 23, went missing during a night out in Bury St Edmunds, Suffolk, on September 24, last year.

He was last spotted walking into a loading bay area in the town and is feared to have fallen asleep inside a bin.

Suffolk Police will have a police pod in Bury St Edmunds on Saturday and Sunday to speak to members of the public.

Officers also issue CCTV stills of individuals they believe may have had some interaction with Mr McKeague on the night he went missing.

After he vanished detectives traced his mobile phone signal showing it had travelled in a vehicle shortly after 4am to Barton Mills around 14 miles away.

The movement of the phone matched that of a bin lorry which picked up rubbish from bins in the loading bay area.

Suffolk and Norfolk police spent five months searching for Corrie at a landfill site in Milton, Cambs, but no trace of the airman was ever found.

A statement from Suffolk Police said: 'Officers would like to stress that the individuals depicted are people who are not key witnesses, are not being treated as suspects and have no direct link with Corrie, but may have information that may help understand what happened to him.'

These men were spotted outside Flex nightclub in Bury St Edmunds at around 1.15am

Detective Superintendent Katie Elliott said: 'Our thoughts are with Corrie's family and friends 12 months on from his disappearance.

'It is fair to say that a year on from him going missing, we never thought we would be in this position of not yet locating Corrie or establishing exactly what happened to him.

'We have always wanted to provide answers to Corrie's family about what happened to him.

'The search for Corrie remains an active investigation. We would appeal directly to the public who were out in Bury St Edmunds exactly 12 months ago on the night he went missing and maybe a year on are once again back in the town centre this weekend.

These people were seen outside the entrance to Flex nightclub in Bury St Edmunds at about 2.23am

'We would ask the public to call us if they have fresh information that may be of benefit to the investigation.

'We have deliberately placed the police pod on Brentgovel Street as we know this is the route Corrie took on that evening and hope our presence will jog someone's memory.

'As we said in July the fact that Corrie wasn't found at the landfill site during our extensive search remains bitterly disappointing to us. We had compelling information that directed us to this particular area of the landfill site.

'The investigation has been a detailed and methodical one to date and this will continue in the weeks ahead.

'The East Midlands Special Operations Unit has been commissioned to conduct a detailed review of the investigation to date.

'The aim of the review is to assist in identifying whether there are any lines of inquiry that could lead to information that would locate Corrie.

'The review is progressing well and is due to be completed in the next few weeks. If it should reveal further lines of inquiry that will help police find Corrie the force will pursue them vigorously.'

Suffolk police announced they were stopping the search for Corrie in July and have now enlisted the help of another police force to review the investigation before deciding what to do next.

Corrie's mum, Nicola Urquhart, 48, is also planning to mark the anniversary of his disappearance on Sunday by returning to the spot where he was last seen.

Anyone with information is asked to contact the Major Investigation Team at Suffolk police on 01473 782019 or 101.
