A second man has been charged over the death of Moses Fadairo, 25, who died in Lower Clapton on September 26.
Bradley Wynter, 28, from Pembury Estate, Lower Clapton, has been charged with firearm possession and assisting an offender.
Wynter was arrested last Saturday and appeared in custody at Barkingside court yesterday.
Christopher Erunse, 27, from Greenwich, was arrested just three days after the killing and charged with murder, attempted murder and possession of a firearm.
Wynter will appear at the Old Bailey in December for a plea and case management hearing.
