A Fairfield University student reported to police that he was assaulted while trying to clear a party out of his on-campus townhouse early Sunday.

Police said five people refused to leave the party and that one punched the host in the face. A woman who tried to break up the altercation was hit in the back of the head, according to the report.

The student had swelling underneath his left eye, but declined medical attention. The woman did not have a visible injury, police said. The assault was reported to police at 12:41 a.m. Sunday.
