A group of Native American students said that they were forced to leave a hockey game in South Dakota over the weekend after men in a box poured beer on them and targeted them with racial slurs.

In a Facebook post, Justin Poor Bear explained that his child was one of the 57 American Horse School students who he accompanied to the Rush hockey game in Rapid City on Saturday night. Poor Bear said that men in a skybox at the Rushmore Plaza Civic Center poured beer down onto the students, who were sitting in a rented suite.

According to the YouTube description, it read:

They were getting drunk and around the third quarter they were talking crap to our kids and throwing down beer on some of them, including our staff and students … telling our students to go back to the rez.”
