The mother of missing Corrie McKeague is urging the "many people" who have not come forward with potentially vital information to do so one month since the RAF serviceman disappeared.

Police recently released further CCTV footage of the 23-year-old who has not been seen since the early hours of 24 September in the Bury St Edmunds area of Suffolk. He had been on a night out with friends and is believed to have intended to walk to his base at RAF Honington.

As part of the investigation, Suffolk Police released details of potential witnesses who they would like to speak to, including a group of people who McKeague sat with in a takeaway before walking off towards Brentgovel Street, as seen on the first CCTV images issued by police.

A Suffolk Police spokesperson said: "There is no suggestion that there was any contact after this, however, police need to talk to anyone who spoke to Corrie in the hours before he disappeared. At this time this group are the last known to have been in conversation with Corrie."

Writing on the Help Find Missing Corrie McKeague, his mother, Nicola Urquhart, is also urging more people who may have seen her son to come forward with information, including the driver of the vehicle seen in the first footage issued by police.

She wrote: "It is now one month since Corrie has last been seen. So many people ask so many questions and feel frustrated, as do we. But so, so many people have still not come forward. The silver car in the first video, we do not know who this is.

"As always there is no suggestion that they had anything to do with Corrie. It's that this person still hasn't come forward. They may know someone else that was about or may have seen other vehicles. Please, I need your help. anyone who was out or knows anyone please let police know."

There were fears that the serviceman's disappearance may have been kidnap as Bury St Edmunds is 30 miles away from RAF Marham, where two men allegedly attempted to kidnap an RAF servicemen by attacking him and trying to bundle him into a car in July. However, police have now downplayed these fears saying that the kidnapping line "has never been a main line of inquiry".

One of the men who was part of the group seen with McKeague at the Pizza Mama Mia in St Andrews Street North is described as wearing a distinctive black T-shirt with the word "Death", the Roman numerals "LXXVIII" and the number "78" in large white letters on the rear and a white motif on the front.
