Police are appealing for witnesses after a group of youths were seen in the vicinity of a deliberate fire at an outdoor sports court in Gamesley.
It is believed to have happened on Monday evening (26 April) at around 7.20pm.
The blaze was reported by a member of the public, who had managed to put the fire out before Glossop's on-call firefighters arrived at the scene on Melandra Castle Road.
