Police were called at about 10.30am on Monday after a visitor to the Armidale cemetery discovered broken boards strewn across the ground near the chapel.
Inspector Chris McKinnon said police were able to identify the juvenile culprits.
“It was a bunch of young kids," Inspector McKinnon said.
"There was a door that was kicked in which caused it to break and brick thrown at the window.
“They were dealt with under the Young Offenders Act."
