SIOUX FALLS, S.D. (AP) — A man serving a sentence for a federal conviction is now facing an escape charge after abandoning a work site in South Dakota and taking off his GPS unit.

Federal court records show Timothy Cadotte has pleaded not guilty to one count of escape. He was sentenced in April 2014 to two years in prison and three years of supervised release for an assault with a dangerous weapon conviction.

Cadotte in March was transferred from a Kansas prison to a half-way house in Sioux Falls, where he was to begin his supervised release term in August. Instead, authorities say, Cadotte left his job at Olive Garden in Sioux Falls on June 27 after removing his monitoring unit.

Cadotte was sentenced after he admitted assaulting a woman in Flandreau in 2012.
