BERKELEY, Calif. – Student protests at the University of California Berkeley are apparently getting so out of hand that the school’s chancellor recently had an escape hatch installed in his office to “provide egress” when students storm the administration building.

Workers spent last weekend installing a special $9,000 door in the hallway outside of Chancellor Nicholas Dirks’ office in California Hall after a series of increasingly aggressive student protests in 2015, including one in which students commandeered the lobby outside of the office and refused to leave, Quartz reports.

University spokeswoman Claire Holmes told The Daily Californian in an email that the new escape hatch is designed to “provide egress to leave the building” as a safety precaution when student protests get rowdy.

According to the news site, “construction of the door was requested about a year ago in response to a protest in April 2015 when protesters stormed the chancellor’s suite.

“During the protest, students staged a sit-in outside Dirks’ office where they banged on desks and chanted loudly. They were eventually escorted out of the building, some in handcuffs, by UCPD officers.”

Students have also targeted Dirks’ home, known as the University House, with large protests and vandalism.

The newly installed escape door was purchased by the UC Office of the President using Be Smart About Safety funding set aside for risk prevention, but some students obviously believe it’s a waste of money.

“There has to be other ways to handle student concerns and protests than simply building ways to avoid them,” student senator elect Chris Yamas told The Daily Californian. “The chancellor seems elitist and out of touch and inaccessible to the students.”

The new escape route comes about four months after the university completed construction on a new $700,000 security fence around University House to keep out the riff raff.

The fence project was initially meant to be a short fence hidden behind hedges, but “increasingly violent attacks on the house” by student protestors convinced university officials a taller, more secure perimeter was necessary, campus spokesman Dan Mogulof told the news site in May.

““The house was attacked and people threw burning torches at it,” Mogulof said. “There were a number of late-night incursions in and around the house.”

The Daily Californian reported:

In November 2015, student activists protesting for workers’ rights marched to the chancellor’s house and jumped over the not-yet completed fence. They proceeded to pound on the chancellor’s door and vandalize the property.

The completed project — designed to prevent such intrusions — includes automatic gates, card readers and cameras for access to the gateways. Additionally, “500 feet of conduits, including electronics” were installed to allow the gates to be operated from within the house, according to the official summary.
