Wichita police are reviewing video from a gas station where two college students say they were attacked by a white man shouting racial epithets and the name of Republican presidential candidate Donald Trump.

Lt. Jeff Gilmore says the video provides a view of the weekend altercation that’s being investigated as a potential hate crime. The Wichita Eagle reports that police aren’t immediately able to determine the accused attacker’s identity.

Wichita State University student body vice president Khondoker Usama, who’s Muslim, says he was pushed and that a Hispanic friend was punched and kicked. A police report says the friend suffered a bruised lip. Usama says a black customer also was called a racial epithet.

Usama says the man left on his motorcycle, after circling and shouting Trump’s name.
