RAPID CITY, S.D. (AP) – Police are now looking into reports of harassment directed at grade-school students from the Pine Ridge Indian Reservation who attended a Rapid City Rush hockey game.

Chaperone Justin Poor Bear says students from the American Horse K-8 school in Allen were subjected to racial slurs and had beer sprayed on them at the Rushmore Plaza Civic Center on Saturday.

Police Lt. Mark Eisenbraun says parents of some of the children called the department, and it has opened an investigation.

Rapid City beer distributor Eagle Sales said earlier that guests in the company’s suite at the Civic Center were responsible for the poor behavior, and apologized.

The company, the hockey team and the civic center all are looking into the matter.
