An 11-year-old girl's wheelchair has been stolen during a Cambridgeshire youth club's outing to Essex.
Thirty children from Bassingbourn Youth Club were swimming at Southend Tennis & Leisure Centre when the theft happened on Saturday afternoon.
Cerys Hennighan has musculo-skeletal problems and her wheelchair was custom-built by the NHS.
The coach's luggage hold was broken into between 13:30 and 17:00 BST when it was parked on Southchurch Avenue.
Her mother Tracey Hennighan said: "Cerys was upset and dismayed and the children were shocked.
"Why does somebody do that and what use are they going to get out of a wheelchair?
"We'll now have to approach NHS wheelchair services to see where we go now, as I have no idea if she'll be eligible for a replacement or if it's covered by coach or Bassingbourn Youth Club insurance."
Essex Police are appealing for anyone with information to contact them.
