A man who crashed a car into the Chinese consulate in San Francisco before he was shot by police was armed with a knife and crossbow, authorities said Thursday.

The man, identified as Zhanyuan Yang, crashed a blue Honda sedan into the building’s lobby on Oct. 9.

San Francisco Police acting commander Mark Im said Yang got out of the car and shielded his face after getting pepper sprayed while swiping a knife at Sgt. Troy Carrasco, who was the first to arrive on the scene, and a consulate security guard.

In body camera video, Carrasco asks “Does he have a gun?” before Yang turns and stabs at him and the guard. Carrasco shoots Yang and admonishes the guard.

“You should have told me he had a knife!” he says.

Yang, 31, died after he was taken to a hospital.

Police later found a crossbow and arrow in the car.

Several 911 calls were made about the initial crash, with one reporting the suspect had a gun.

Yang’s motives were not clear.

“Why he showed up there, what he was doing, that’s still under investigation and there’s nothing that we have at this point that I can release,” said San Francisco Police Chief Bill Scott.

No other injuries were reported in the crash.

“A consulate is a place of safety and refuge where people should not have to worry about acts of violence,” SFPD captain Jason Sawyer said on Thursday. “This was a highly unusual event that could have easily involved many more casualties.”
