LANSING, Kan. (AP) — A minimum-security inmate at a northeast Kansas prison is back in custody after reportedly walking away from a work detail.

The Leavenworth Times reports 52-year-old Ronald J. Emons was apprehended without incident late Monday afternoon at or near Fort Leavenworth.

Emons is serving time at the nearby Lansing Correctional Facility for violating his probation for a conviction of attempted indecent liberties with a child.

KAIR Radio reported that Emons went with a work crew around 6 a.m. Monday to a reservoir outside the prison compound’s fenced area. Staff noticed him missing around 10:40 a.m.

A judge sentenced Emons in July 2011 to probation for attempted indecent liberties with a 14- to 16-year-old child. He has been sent to Lansing twice for violating the terms of his probation.
