The Sleepy Theatre and Arts Park in Bismarck was vandalized over the weekend.

KXMB News reports the Sunday show was canceled as a result. The theatre has not yet issued word on the scheduling for later this week.

The show scheduled for this week is the Biblical rock opera, "Joseph and the Amazing Technicolor Dreamcoat."

Police report the vandals took videos of themselves in the act and posted them on social media over the weekend.

The vandalism apparently happened Sunday afternoon, primarily in the backstage area.

KX says the floors, doors, and mirrors were spray-painted. The light bulbs above the mirrors were smashed, leaving shattered glass on the counters and on costumes. Damage is estimated at about $1,000.

The theater posted a message of its own on social media saying the vandals were "kids in pain. We know that they did not know what they were doing."

"Please if you have any information, let us know."
