A Periscope user captured this video of the aftermath at Fourth and Brannan, though they incorrectly assumed that a bank robbery had taken place.

We've reached to CHP for more information and will update this report as we learn more. So far, we know that the officer was taken to SF General Hospital.

Update, 12:30pm: At a noon press conference, SFPD and CHP personnel shared more details on the incident. According to CHP's Christopher Sherry, CHP officers responded to a call of a person in the road on the Essex Street on-ramp, but responding officers could not locate the person. A two-person unit arrived about 10 minutes later, Sherry said, and made contact with a man adjacent to some tents on the side of the ramp. The suspect allegedly attacked one the officers, a seven-year CHP veteran, then ran from the scene while the second officer administered first aid to the victim, who sustained "pretty significant injuries." 

At around 10:22am, SFPD located the suspect inside the Wells Fargo branch at Fourth and Brannan. He was taken into custody without further incident, and a knife was recovered.

According to Sherry, the victims sustained a life-threatening injury, but was in stable condition.

Update, 2/3: The suspect has been identified as 44-year-old Noel Corpuz, and booked at County Jail for attempted murder, aggravated assault, and resisting arrest. 

Police report that the victim is out of surgery and in stable condition.
