Youths with aerosols are believed to have started a fire Sunday night.
Firefighters were called to St Nicholas Avenue in Rowner at around 6pm last night to tackle a burning pile of rubbish on an area of park land.
The alarm was raised by a nearby resident who reportedly saw a group of teenagers playing around with aerosol cans before fleeing the scene.
A crew from Gosport fire station spent about half an hour putting out the blaze, and found burnt out aerosol cans in the debris.
No-one was hurt during the incident.
