Troy Carpenter, 18, of San Francisco, allegedly escaped from San Francisco's Northern Station on Nov. 26 while awaiting booking in connection with several of the robberies. He fled into a nearby neighborhood.
Five others -- including Carpenter's twin sister: 18-year-old Troyetta Carpenter, a 27-year-old Hayward man, and three juveniles -- were arrested on Nov. 13 in connection with at least five robberies the previous week in the Mission District and Lower Haight, Tenderloin-Nob Hill, Lower Pacific Heights and Cow Hollow neighborhoods.
An investigation subsequently linked Troy Carpenter to the robberies as well, police alleged.
Police said that in all of the robberies, the victims were sprayed in the face with pepper spray, assaulted and robbed. Some of the stolen items were later recovered.
After Carpenter's escape from the police station, officers undertook an "extensive manhunt" that led them on Monday to Elk Grove, where they arrested Carpenter as he was driving away from a home, police said.
Carpenter was booked into San Francisco County Jail on charges of robbery, escape, and possession of crack cocaine for sale -- all felonies, according to police.
He is now suspected in connection with a total of six robberies, police said. His bail has been set at $505,000, and he is due in court Tuesday.
