Officers responded to a noise complaint in an apartment building in the 1000 block of Sutter Street at around 11:10 a.m., Sgt. Troy Dangerfield said.
Officers had received reports of an intense verbal argument and of someone – possibly a tenant – throwing stereo speakers out the window of a seventh floor apartment, Dangerfield said.
Police went to the apartment with the building’s manager to make contact with the involved parties.
At some point during the investigation, an occupant of the apartment pulled out a weapon and the investigating officer fired his gun, fatally wounding the suspect.
The suspect, an adult male, has not been identified.
It was not known what weapon the suspect was holding that prompted the officer to shoot, and police did not say how many rounds were fired.
The shooting is being investigated by the police department’s internal affairs department, the homicide unit and the San Francisco district attorney’s office.
