OMAHA, Neb. (AP) — Nebraska officials have agreed to release an inmate who was sent back to prison amid questions about miscalculated sentences.

The Nebraska Attorney General’s Office said Wednesday that David Amesbury qualified for time already served and should be released immediately.

Amesbury was originally released from prison in 2012 after serving more than 10 years. He was rounded up in June amid questions of whether hundreds of inmates were released early from prison.

Amesbury filed a lawsuit challenging his return to prison. His attorney argued that Amesbury was given an illegal sentence because a judge improperly gave him a separate sentence for a habitual criminal charge.

Amesbury’s release marks the second time state officials have released an inmate rounded up in June.
