An arrest has been made after an attack on a conservative activist on the University of California-Berkeley campus was caught on camera.

Zachary Greenberg, 28, was arrested on a warrant on Friday at in Berkeley, California, following a 10-day search, according to the San Francisco Chronicle.

He was held on $30,000 bail in Alameda County jail on suspicion of assault with a deadly weapon likely to produce great bodily injury for the attack on Hayden WiIliams on February 19.

He is to be arraigned on Monday at the Wiley W. Manuel Courthouse in Oakland.

Neither Greenberg or Williams are students at the University of California-Berkeley.

In a statement to Campus Reform, Williams expressed his view of the news of his attacker's arrest:

'I am grateful to the University of California Berkeley Police Department for its dedication to identifying and arresting the man who attacked me. But while this is a moment for celebration, I remain disappointed by the UC Berkeley Administration, which allowed a culture of intolerance and violence toward conservatives to grow. I hope UC Berkeley’s leadership will seize on this moment-in-time to take deliberate steps to establish a zero tolerance policy when it comes to violence, and restore Berkeley’s legacy as ‘Home of the Free Speech Movement.'

Williams was running a campus recruitment table for Turning Points USA, a conservative activist group, when he was approached by his attacker in Sproul Plaza.

The sign on the table read 'hate crime hoaxes hurt real victims,' a reference to the Jussie Smollett the bias incident allegedly staged by the actor himself in Chicago.

The suspect shouted: 'Mother f**ker. You racist little inbred b***h. C**t!'

UC-Berkeley campus police said that the attack took place at 3.29pm on Upper Sproul Plaza, and that two men initially approached the table confronting Williams.

'A physical confrontation ensued when one of the two men slapped the phone out of the victim’s hand,' the police statement said.

The attacker then knocked over the table and the two men fought over the phone.

During the incident, the suspect punched the victim several times causing injuries to the eye and nose.
