Robert Arnold is now officially the former Rutherford County Sheriff after pleading guilty to corruption charges, and later resigning as sheriff.

As a part of the plea agreement, Arnold has agreed to pay $52,500 in restitution to Rutherford County.

Arnold plead guilty to 3 counts of public corruption, wire fraud, honest services fraud and extortion.

Arnold originally faced up to 60-years in prison, but with the plea arrangement, he might only have to serve four-to-six years. That will all be determined when the judge makes a ruling.

The former sheriff asked to be released from the Grayson County Detention Center in Leitchfield, Kentucky. His attorney requested that Arnold be allowed to stay with his mother until the sentencing. However, the judge ruled that for the time-being, he would remain incarcerated.

A sentencing date was set for May 8, 2017.

Former jail administrator Joe Russell and Arnold's uncle, John Vanderveer are also both expected to reach plea arrangements. Russell has a hearing in federal court on Friday.

By pleading guilty to these federal offenses, Arnold is unable to serve as a peace officer. It has been confirmed that after the hearing, Robert Arnold resigned as sheriff of Rutherford County
