(CNN) A conservative activist reported he was attacked while recruiting students for Turning Point USA at UC Berkeley, according to campus police.

The University of California Police Department said in a statement that officers responded Tuesday afternoon to a "report of a disturbance" on upper Sproul Plaza, a center of student activity on campus, where they found the injured victim. An investigation is continuing, the university said Friday.

According to the police statement, the victim said that two men approached him, a verbal altercation ensued and he began recording the interaction on his phone.

One of the men "slapped the phone out of the victim's hand," police said. "The suspect then knocked over the table the victim was at and the two men struggled over the phone. During the incident, the suspect punched the victim several times causing injury to the victim's eye and nose."

Turning Point USA later identified the alleged victim to CNN as Hayden Williams, who had been invited to UC Berkeley to help recruit students for a yet-to-be-formed chapter on campus.
