A D.C. police officer used his squad car to drive an accomplice to the scene of a robbery, then watched as one of the robbers was fatally shot, according to court papers.

Officer Reggie Jones was handcuffed Tuesday by fellow officers and charged with felony murder. Police say he plotted and helped carry out a drug crew’s robbery of a rival dealer in Southeast on Dec. 1. During the incident, a member of the crew opened fire, accidentally killing fellow robber Arvel Alston.
