Rock, 34, of Pontotoc was indicted in late May and faces up to two years in prison and $500,000 fine or both, if convicted.
His indictment only recently was made public.
Rock is accused of making two traffic stops in Ecru on June 7, 2008, and demanding cash from each driver to avoid a traffic ticket.
The indictment claims that Rock, acting “under the color of laws” as a police officer, deprived these two drivers of their constitutional rights against unreasonable search and seizure.
A spokesman at Ecru Town Hall confirmed that Rock no longer works there.
A warrant was issued for his arrest May 22, but no other actions in the case are on the public docket.
