SAN FRANCISCO -- San Francisco police surrounded a building on California Street near Hyde Street this evening after a possibly-armed resident made threats against a neighbor, according to a San Francisco police spokesman.
Police were called to the building on the 1400 block of California Street around 6:30 p.m. after a resident overheard a domestic dispute next door, Officer Carlos Manfredi said.
When the resident tried to check on his neighbor, the neighbor made what Manfredi called "credible threats" against him.
Officers arriving on the scene attempted to make contact with the suspect, but determined that he might have a weapon inside the apartment and "erring on the side of caution" chose to step back outside, Manfredi said.
The surrounding units were evacuated and other nearby residents have been told to shelter in place.
Hostage negotiators have been called in to talk with the suspect, but Manfredi said at this point police are unclear whether there is anyone else in the apartment with him.
Police have closed streets in a one-block radius around the building, according to Officer Carlos Manfredi. The closure has affected service on the California Street cable car line between Hyde and Larkin streets.
The American Red Cross is on the scene assisting residents displaced by the incident, Manfredi said.
