Maurice Carter, 27, of the 1600 block of Pratt Street in Philadelphia, was arrested Wednesday night as he walked on Frankford Avenue.
Police say the officers who arrested Carter had previous dealings with him, and knew he was wanted in the killing of Oscar Hernandez on October 14th.
Carter is charged with murder and is awaiting extradition to New Jersey.
Carter is one of three men accused of entering Alex's Bakery on the 1600 block of Ferry Avenue about 8:45 p.m. on October 14 intending to rob the business.
During the course of the attempted robbery one of the three men shot the bakery's owner, Hernandez, in the chest, killing the 29-year-old Woodlynne man.
The three suspects are accused of leaving the bakery after being unable to open the register.
Arrested on October 29 in Camden were William Cooper Jr., 31, of Branch Village in Camden, and Rashawn Carter, 24, with addresses in Camden and Philadelphia. Both are also charged with Felony Murder. Cooper is accused of shooting Hernandez.
Rashawn Carter and Maurice Carter are brothers.
