Update, 3:58 pm: UC Berkeley has confirmed that police fired the shots in today’s shooting incident. Here is their statement published on the News Center website:

Campus officials report that a shooting took place Tuesday afternoon at the Haas School of Business.

The suspect was seen carrying a gun. A staff member reported this to the police, who responded immediately. The suspect entered a computer room, where police followed him and asked him to put up his hands. The suspect then pulled out the gun, and police shot him.

The area is now contained, and the Haas School has been evacuated until further notice.

The police remain on the scene, and the victim is en route to the hospital. No other injuries have been reported, and there is no indication of other shooters.

UC Berkeley’s Warn Me system has been activated by police, but the campus is not asking the community to shelter in place.

Updates of this incident will be forthcoming.

Update, 3:45 pm: We have confirmation, from UC Berkeley spokesperson Dan Mogulov of the following:

Earlier this afternoon a staff member at the Haas School was riding in the elevator. They saw a man who was carrying a firearm in his bag. The staff member informed their supervisor when they got off the elevator. The supervisor called law enforcement (UCPD) who came to the school.

The police found the identified person in the computer lab and shouted “Drop the gun”. Shots were fired. Mogulov could not confirm who shot or how many shots were fired. Berkeleyside spoke to one person who was at the front desk of the computer lab who said he heard four or five shots after hearing the words “drop the gun” being spoken.

The suspect is also the victim. He was alive when he was taken to hospital. The name of the hospital has not been confirmed, and the condition of the victim is not known at this time.

“All students, faculty and staff are safe,” said Mogulof. “We have no idea who the suspect is. We have no idea why he was here.”

The Haas School is going to be closed for the remainder of the day because it is a crime scene.

A press conference is being held at 4:00 pm and we will keep providing updates.

Update, 3:15 pm: According to UCPD spokesperson Alex Yao, the suspect and the victim are one and the same in this incident.

Update, 3:14 pm: According to witnesses on campus talking to media reporters on the ground, including KTVU and California Beat, there may be one suspect in the shooting and he or she may have been taken into custody. The shooting is believed to have occurred in a third-floor computer lab at the Haas School of Business and as many as 10 shots may have been fired. We will provide confirmation and updates as soon as we have them.

Update 2:59pm University spokesman Dan Mogulof told Berkeleyside that there had been a shooting at Haas and the victim had been transported to the hospital. The Haas School has been evacuated. Mogulof is now meeting with UC Police.

Original story: According to ABC News, reporting via Twitter, UC Berkeley spokesperson Dan Mogulof has confirmed that there has been a shooting at the Haas School of Business on the Cal campus.

It’s an Occupy Cal Day of Action on campus today but it is not clear whether the alleged shooting and the demonstrations are related.

Ericka Lutz on Twitter reports that she had received a UC Warn Me text saying “Shooting at Haas, police on scene and all under control, avoid the area”.

We will keep providing updates as soon as we have them.
