A shooting occurred at UC-Berkeley today at the Haas School of Business at approximately 2:30 p.m., according to Berkeley officials at a press conference Tuesday afternoon.

The Berkeley Police Department (UCPD) shot the suspect, a white, 33-year-old male. Four students were present at the time of the shooting, which occurred in a computer lab on the third floor, according to an ABC East Bay News report. It has not been confirmed whether or not the suspect is a student.

A Haas staff member saw the suspect carrying a backpack and a gun, prompting the staff member to notify a supervisor who called the UCPD.

At least one UCPD officer shot and wounded the suspect, although the number of shots remains unconfirmed. The victim was transported to Highland Hospital.

The business school was evacuated after the shooting, and classes in the building were canceled for the rest of the day. According to an email sent to Haas students by Jay Stowksky, senior dean for instruction at the school, no one other than the suspect was harmed. UC officials say there is no remaining threat to students.

A link between the suspect’s activity and the Occupy Cal protests currently happening on Berkeley’s campus and in the surrounding area has not been confirmed, according to Berkeley’s Chancellor Robert Birgeneau and UCPD Police Chief Mitchell Celaya at the press conference.

Berkeley and Stanford students will come together for a student-organized Occupy march on Stanford’s campus this Saturday afternoon, starting at the Arrillaga Center for Sports and Recreation. Several hundred students have registered for the Facebook event.
