Former Black Panther leader Huey Newton, who last week refused to leave San Quentin Prison in California on his scheduled released date, walked out of prison Friday.

Newton had told prison officials on Tuesday, when his two-month sentence for a parole violation expired, that he would not leave unless former comrade Elmer "Geronimo" Pratt also was released.Newton's protest was the first time he had publicly come forward in Pratt's support. Pratt has been in prison for 18 years for a murder he claims he did not commit. At one time, the two radicals were enemies within the Black Panther party.

"I could better serve his campaign for freedom outside the walls of San Quentin," Newton said after his release. "Geronimo asked me if I would leave even though he's very touched by the support I gave him."

Pratt and his supporters claim the FBI framed him for a 1968 Santa Monica murder as part of its late 1960s efforts to break up radical groups like the Black Panthers.
