An 18ft trailer containing the children's roundabout ride was snatched near a service station in Fife.
An 18ft trailer containing a children's fairground ride worth £40,000 has been stolen from near a service station in Dunfermline.
The roundabout was parked by the owners on the service road approaching Kingdom Services in Halbeath, along with another ride.
It was taken sometime between 18:00 on Tuesday 31 December and 13:00 on Friday 3 January.
Police say the thieves must have used a high powered vehicle with towing equipment to make off with the trailer.
Community Sergeant Darren Stewart, who is co-ordinating enquiries, said: "This is quite an unusual theft concerning a high-value piece of showground equipment.
"The ride itself is pink and blue in colour with Disney characters on the top and has several horses, a red bus, a fire engine, a car and dolphins for children to ride on or in.
"I am asking for anyone who may have witnessed this theft or to anyone connected with this industry who may been offered the ride for sale to contact the Police in confidence."
