Authorities are looking for the vandal or vandals who used rocks to break several windows in the Minnehaha County Courthouse in Sioux Falls Monday night or Tuesday morning.

Jail Warden Jeff Gromer says there are no suspects so far.

He says it happened sometime after midnight, and the incident is under investigation.

Gromer says anyone with information should contact the Sheriff's office.

He says there is surveillance video of the building, but he doesn't know yet if it will help authorities find the culprit.
