WICHITA, Kan. (AP) — Wichita police are investigating a report that two college students were attacked by a man shouting racial epithets and the name of Republican presidential candidate Donald Trump.

Wichita State University student body vice president Khondoker Usama, who is Muslim, said he and a Hispanic friend witnessed a white man calling a black customer a racial epithet at a convenience store before the man turned on him and his friend Saturday.

Usama said he was pushed, and that his friend was punched and kicked. Usama said the man then rode away on his motorcycle, after circling them and shouting Trump’s name. A police report says the friend suffered a bruised lip.

Police Lt. Jeff Gilmore told The Wichita Eagle that officers are seeking surveillance video from the store.
