Police have arrested the man suspected of injuring another man at a table for a conservative student group on Upper Sproul Plaza at UC Berkeley.

An Alameda County Superior Court Judge issued a warrant for the arrest of suspect Zachary Greenberg.

Grrrenberg was arrested by the University of California Police Department and booked into jail at 1 p.m.

According to UC Berkeley officials, "UCPD will formally present the case to the Alameda County District Attorney’s Office for consideration of the filing of criminal charges."

UC Berkeley student who witnessed the attack last month told officers that two men had been fighting.

On the plaza, officers found an injured man who said he had been punched several times. The victim told police he was at a table for the student group Turning Point USA when two men came up to the table and started arguing.

Video provided by Alexander Szarka shows an attack at UC Berkeley’s Sproul Plaza.

The victim started filming the argument with his phone and apparently a fight began when one of the two men slapped the phone out of the victim's hand.

The suspect knocked over the table for Turning Point and the pair struggled over the phone. Then the suspect punched the victim several times, injuring the man's nose and eye, police said.

The suspect left the plaza before officers arrived.
