Police east of Ottawa are trying to find the culprits behind a rash of graffiti painted on property throughout Rockland, Ont.

Ontario Provincial Police say the incidents began in November 2011 and are becoming more rampant.

The targets listed include Rockland District High School, L’Escale High School, Park Simon, Dalrymple Park as well as a bandstand, tennis court and three stores.

The graffiti has cost the city thousands of dollars to clean and paint over, police added.

The investigation continues and police say they need the public's help.

If anyone has information on the graffiti they should call Det. Paul Dube at 613-446-5124.
