Police in Haverhill have asked for people out walking at the back of Clements Primary School to remain vigilant and tell them if they see anyone trespassing on the schools grounds.
The request has been made after the police received reports of people using the outdoor classroom area in the school’s grounds as a place to hang out.
PCSO Lorna Chapman, from Haverhill Safer Neighbourhood Team, said: “We had problems with it last year being damaged and apparently anti-social behaviour is starting again.
“If any walkers, or anyone else, sees someone in that hut, they should not be on the school premises, so please call 101.
“I don’t want to see it happen again.”
