Protesters tore down barricades, let off fireworks and set the campus ablaze during the furious protests over the conservative Breitbart editor.
Hundreds rallied against Yiannopoulos in a demonstration which turned violent and destructive, with protesters vandalizing dozens of businesses and smashing storefront windows. University police locked down all buildings and responded with tear gas and rubber bullets, according to witness reports.
Yiannopoulos himself later posted a video complaining that UC Berkley was 'no friend to free speech any more.'
The journalist said he had been planning to speak about cultural appropriation but claims his speech was over taken by the 'hard left.'
'It turns out the progressive left... which has become so antithetical to free speech has taken a turn post Trump's election. Where they simply will not allow any speaker on campus even someone as silly and harmless and gay as me, to have their voice heard.
'They are absolutely petrified by alternative visions of how the world could look.'
He added that it was both 'ironic and sad' that the campus was the home of the free speech movement, but it was 'no friend to freer speech any more.'
'I am of course not the racist or sexist or anything else that the posters that they put up claim that I am.'
University police confirmed that the campus was on lockdown as they reported they were bringing in extra resources to tackle the 'violent demonstration.'
'Milo event cancelled. Shelter in place if on campus. All campus buildings on lockdown. #miloatcal,' they tweeted.
President Donald Trump reacted to the massive rioting at UC-Berkeley in response to a scheduled campus speech by Breitbart News editor Milo Yiannopoulos.
“If U.C. Berkeley does not allow free speech and practices violence on innocent people with a different point of view – NO FEDERAL FUNDS?” Trump wrote on Twitter early Thursday morning.
If that doesn't calm things down- and I would be very surprised if a few slaps upside the head with a big stick don't work- then that is why God, in His infinite wisdom, gave us the bayonet.
And if that doesn't work, well, He thought of that too. Which is why we also have the M-16 and the FN SCAR.
I do not advocate for this lightly. I have personally seen what happens when a nation tears itself apart in an orgy of looting, violence, rape, and burning. Those memories are seared into my brain to this day. I will never forget that cold dread in the pit of my stomach that I felt when I saw huge plumes of smoke rising up above the city that I had called my home for 7 years as the riots that eventually deposed President Suharto consumed the city of Jakarta in 1998.
I do not wish such a fate on any country, least of all one that I love as much as I do America.
But if this is what things have come to, then let it be done.
