LANSING, Kan. -

A man who walked away from a work detail in northeast Kansas is back in custody.

Fifty-two-year-old Ronald J. Emons was being held at the Lansing Correctional Facility for violating his probation for a 2011 conviction of attempted indecent liberties with a child.

KAIR Radio reports 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.

Jeremy Barclay, Kansas Department of Corrections spokesman, said Emons was apprehended near Fort Leavenworth around 4:15 p.m. Monday. He was taken into custody without incident.

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.

New escape charges are pending.
