School officials are investigating.
Shane Schuster, 19, said he was seated with some friends at Ralph Engelstad Arena when something in the Red River High School student section across the rink caught his eye midway through the first period.
“I thought, ‘Are those KKK hoods?’ I couldn’t believe it,” he said. “I was shocked.”
Schuster, a University of North Dakota student, said he focused his camera phone and snapped a photo, later uploading it to Twitter. The hoods were on for about 10 to 20 minutes, he estimated, but they were removed by the second period.
Mark Rerick, the Grand Forks Public Schools’ athletics director, said Saturday that he conferred with arena and tournament security staff immediately after learning about the picture.
“After confirming the incident, we notified the administrators at Red River High School who immediately began their investigation,” Rerick said in a statement emailed to the Associated Press. “To the best of my knowledge, the students have been identified by the Red River administrators who are continuing their investigation.”
