Two Atlanta contractors have been sentenced to prison as part of an ongoing federal investigation into bribes paid for city contracts.

A judge on Tuesday ordered Elvin R. Mitchell Jr. to serve five years in prison and to pay more than $1.12 million in restitution. The other contractor, Charles P. Richards Jr., was sentenced to serve two years and three months in prison and to pay $193,000 in restitution.

Each pleaded guilty earlier this year to a conspiracy charge.

Prosecutors say Mitchell and Richards conspired to pay city officials to award them lucrative city construction contracts, with more than $1 million paid out between 2010 and 2015.

Mitchell's lawyer, Craig Gillen, said his client hopes to have his prison time reduced as he continues to cooperate with prosecutors.
