(AP) -- Officials at Iowa State University are investigating three students accused of sending threatening and racial tweets to a University of Kansas basketball player after a heated overtime game.
Dean of Students Pamela Anthony says Thursday the tweets about KU guard Elijah Johnson were reported to the university earlier this week.
She couldn't provide more information because of federal privacy rules.
Anthony says the school is "repulsed by the derogatory and threatening statements."
Johnson angered some ISU students when he dunked the ball with seconds left during an overtime game Monday between the Jayhawks and the Cyclones.
Some fans hurled plastic megaphones at KU players after the Jayhawks' 108-96 win.
Johnson apologized for the dunk at a postgame news conference.
