Yiannopoulos is an openly gay conservative editor for Breitbart News who has criticized feminism, transgender rights, Islam, and the Black Lives Matters movement. Yiannapolous was invited to speak on campus by the Davis College Republicans.

After the event was canceled, he posted on Facebook that isn’t being allowed near the building because police “can’t guarantee everyone’s safety.”

A UC Davis police spokesperson says there were no broken windows and no reports of hammers. One person was reportedly arrested inside of a building during a security sweep for resisting arrest.

Hundreds of students petitioned earlier in the week to have the event canceled, but the interim UC Davis chancellor said he would not ban Yiannopoulos from speaking.

“So right now we need to be more brave and stronger about saying no to the spread of hate speech in our communities,” said UC Davis student Emily Breuninger.

Controversial former pharmaceutical executive Martin Shkreli was also scheduled to speak at Friday’s event.

After the event was canceled, Shkreli appeared briefly and took pictures with some of his fans before being jostled and shoved by protesters then quickly whisked away by police officers.
