Bedfordshire Police are appealing for information after a fire was started in Bennett Memorial Recreation Ground in Dunstable.
Officers were called at 9.10pm last night (Tuesday) with a report that some youths had started a fire in the new play area, Bennett's Adventure Play, in Bull Pond Lane, Dunstable.
A spokesperson for the force said: "Emergency services attended and found that an accelerant, believed to be petrol, had been used to set light to play equipment, destroying a climbing frame.
"The offenders had left the scene by this time, so if anyone was in the area at this time and saw anything suspicious, please call 101 quoting reference 436 of 28 August."
Bedfordshire Fire and Rescue sent one fire engine to the scene, a spokesperson said: "We were called at approximately 9.05pm to reports of a small fire at a play area in Bullpond Lane, Dunstable. One fire engine attended and extinguished the fire."
