Officers say sections of graves were used to set a circle for a fire
Police in Northern Ireland say one of their patrols was attacked with part of a gravestone on Sunday night.
It happened as they were driving through the Falls Park area of Belfast.
The PSNI say an individual threw a large corner stone at their vehicle.
And while patrolling on foot, officers say someone had also taken sections of people's graves to use them to set a circle for a fire.
A post on their Facebook page, entitled "What is wrong with you?", says: "Imagine how distressing this is for the family who's loved one isn't being allowed to rest in peace.
"These are sickening acts that show absolutely no respect for the local community."
They are appealing for anyone with information to contact them.
