Vandals struck the Rapid City campus of United Tribes Technical College over the weekend, three days after the Bismarck, N.D.-based school held a grand opening celebration for its Black Hills Learning Center.
Officials say the vandals targeted doors and windows early Saturday and caused as much as $75,000 in damage. Police are investigating.
A $5,000 reward is being offered for information that leads to an arrest.
Classes at the school are scheduled to begin Aug. 26.
