A photo of the hood-wearing trio was posted on Twitter by University of North Dakota student Shane Schuster — who was taking in the game at the university's Ralph Engelstad Arena in Grand Forks — during a state playoff game between North Forks (N.D.) Red River High and Fargo (N.D.) Davies High.
Schuster posted the photo with the message: " I guess the red river highschoolers are racist?"
The racist garb was apparently a knuckle headed attempt to join in on the Red River fans' whiteout — where the spectators flood the stands in white duds.
The three unnamed culprits are reportedly all freshmen who put on the offending hoods for about 30 seconds before they were angrily told to remove them by surrounding fans, said witnesses.
Red River principal Kris Arason has already identified the teens who donned the hoods, reaching out to their parents and telling the press that "appropriate action is being taken."
"We, as a school, are extremely disappointed with the behavior of these three students," Arason said in a statement. "This behavior is not a representation of our school or student body."
Red River defeated Davies 2-0.
