Sgt. John V. Young, 51, was killed in the attack, which also injured a civilian clerk at a city police station.
The suspects were members of the Black Liberation Army, a violent offshoot of the Black Panther Party, authorities said.
The names of the suspects weren't immediately released, but San Francisco police planned a news conference later in the day, Sgt. Neville Gittens said.
Three men were charged in the attack in early 1975. However, those charges were dismissed by a San Francisco judge because of an earlier ruling that evidence was obtained by torture after the suspects were arrested in New Orleans.
