A rash of late night vandalism in Spruce Grove and Stony Plain has prompted RCMP to write an open letter to parents asking them to keep an eye on their kids.

According to the letter, there have been more than 30 incidents of vandalism and property damage since school ended two weeks ago.  

"There have been about 13 or 14 deliberately set fires. As well there has been some spray painting incidents, some mailboxes turned over and just general mayhem,” Cpl. Colette Zazulak said.

Most of the incidents occurred between 3 and 6 a.m. Zazulak is asking parents to step up.

“We want parents to know that first and foremost, they are responsible for their children,” she said. “The onus is on the parents to ensure their children are home in their beds during those hours.”

Vandals have also burned large holes in slides at playgrounds. Fires set in garbage cans and portable toilets at constructions sites could also cause greater damage, Zazulak warned.

"With the warm weather things are really dry right now and we have new homes under construction, fires being set close to there,” she said. “There's a lot of potential for damage."

RCMP have arrested a couple of young people and charges are pending.

Police are asking witnesses to call if they see anything.
