The family of missing Corrie McKeague are urging people not to turn up to a search taking place tomorrow unless they have already been given a place.
The RAF serviceman disappeared following a night out in Bury St Edmunds almost three months ago.
His mother, Nicola Urquhart, says they have enough volunteers already and is worried if too many people turn up, it could be dangerous.
In a Facebook post she wrote:
The criteria is strict for a number of reasons, your safety being paramount, but secondly because to have the support of SULSAR (Suffolk Lowland Search and Rescue) and Suffolk Constabulary I must ensure that these searches are carried out with the same level of professionalism and thoroughness that has been used in every search for Corrie so far.
If a search is carried out and not done correctly this could mean Corrie is not found. It will be believed that Corrie is no longer in that area, that is a situation I do not wish to put my boys our families or myself through.
Suffolk Police are releasing CCTV images of potential witnesses as work continues to trace missing Corrie McKeague.
All of the images show individuals in Bury St Edmunds town centre between 3.15am and 5.20am who have not yet been traced.
Detective Superintendent Katie Elliott is appealing for those pictured to come forward.

A crowdfunding campaign to hire a private investigator to search for missing RAF serviceman Corrie McKeague has exceeded its £20,000 target in less than two days.
23-year-old Corrie was last seen in the early hours of 24 September in Bury St Edmunds, Suffolk.
He was reported missing when he failed to turn up at his base, RAF Honington, 10 miles from the town.
A JustGiving page was set up later by Cheryl Hickman, who runs the Suffolk hotel where Mrs Urquhart has been staying since her son went missing.
The fundraising page said donations would be used to fund the appointment of a private investigator and a data analyst to go through the information gathered.
Mr McKeague's grandparents had earlier pledged a "five-figure reward" for information leading to his safe return.
