Cushions and firelighters were stolen from a community centre in Seaford and then torched on Tuesday May 21.
Sussex Police have warned parents to keep an eye on their children as half term approaches following the break-in at the Florence House Community Centre at the back of Southdown Road in Seaford.
The grounds were entered overnight and items were removed from a yurt building used for classes.
These items were then taken to an area at the edge of the nearby golf course and set on fire.
Sgt Stuart Mullins, from Seaford’s Neighbourhood Policing Team, said: “We are keeping an open mind about this matter but it may be linked with a series of incidents that we had over the weekend involving a group or groups of youths.
“I would urge all parents to be wary if their children stay out all night.
“They might tell you that they are staying with a friend, and the friend’s parent is told that they are staying with you.
“It is always worth checking their whereabouts.
“With half term coming up and older children beginning study leave we don’t want teenagers roaming around all night, getting up to mischief and even criminal activity.
“What might start off as messing about can have more severe consequences.
“Criminal damage, theft and burglary are all serious offences that can result in arrest and, at worst, imprisonment. By all means have fun but don’t engage in antisocial behaviour.”
Anyone who has information about the burglary, or who witnessed what happened, is asked to call police on 101 quoting serial 0299 of May 22. Alternatively, call the independent charity Crimestoppers anonymously on 0800 555111.”
