Detectives are hunting a group of teenage boys and girls after a trailer was set alight in Glasgow causing around £80,000 worth of damage.
The fire was started in a yard in the Swanston Street area of the city overnight on Thursday into Friday.
The trailer contained a section of a fairground ride, which was significantly damaged in the blaze, police said.
Officers said it was “fortunate” the fire did not spread further and cause even more destruction.
Police have established that four youths were seen in the area around the time of the incident.
They are described as being two boys and two girls between the ages of 14 or 15 years old.
Efforts to identify them and establish the circumstances remain ongoing, Police Scotland said.
Detective constable Ross McGill, from Shettleston CID, said: “This fire caused a great deal of damage to the trailer and its contents, although it’s fortunate it didn’t spread even further and cause more destruction.
“We are appealing for anyone with information to come forward. We’re also keen to speak with the four young people who were in the area, so would appeal for them to come forward or for anyone who can identify them to do so.
“If you believe you can assist our enquiries, please call police on 101, quoting incident 0155 of June 24. Alternatively, you can call Crimestoppers on 0800 555 111, if you wish to remain anonymous.”
