The Saskatchewan Party's headquarters in Regina was the target of vandalism over the weekend.

The window of the Rochdale Boulevard building was vandalized with blue spray paint saying "crook."

The incident happened early Sunday at around 1:30 a.m.CST, according to security camera footage released on the Saskatchewan Party's Twitter account.

Premier Brad Wall tweeted about the graffiti on Sunday afternoon.

"Last night some jackwagon vandalized @SaskParty HQ w/ graffiti," he wrote.

Patrick Bundrock, executive director of the party, said they were able to wash the graffiti off but he is still disappointed.

"This is something that should happen to no candidate, no political party," Bundrock said. "This campaign should be about the issues and the ideas."

The provincial election in Saskatchewan is on April 4.

Wall asked anyone who recognized the "said jackwagon" to call Regina police at 306-777-6500 or call Crime Stoppers at 1-800-222-8477 or report online.
