Arrest made in North Beach shooting during attempted mugging.

San Francisco police have arrested Malachi Lefiti, a 22-year-old man from Oakland, in connection with a shooting that killed one man and injured four others in the city's North Beach neighborhood on Sunday. The police say that Lefiti and other suspects were attempting to rob victims at gunpoint, which led to an altercation and the shooting. The deceased victim has been identified as Isaiah Thomas from Suisun City. The other victims, including Lefiti, were taken to a hospital with non-life-threatening injuries. The police believe the shooting was an isolated incident and not random.
