As previously reported, a violent leftist attacked a Turning Point USA activist who was out recruiting for their chapter at UC Berkeley last Thursday afternoon in Upper Sproul Plaza.

The assault was captured on video and posted to Twitter by Turning Point USA founder Charlie Kirk.

On Friday, Zachary Greenberg was identified and arrested by UC Police — law enforcement booked him into jail at 1 PM.

CBS San Francisco reported that police will formally present the case to the Alameda County District Attorney’s Office for consideration of the filing of criminal charges, the university said.

Just one day before Zachary Greenberg’s arrest, Citizens United Foundation offered a $50,000 reward for information on the thug who beat conservative activist Hayden Williams.
