LINCOLN, Neb. (AP) — Six Nebraska prison staff members have been disciplined in the wake of an escape of two inmates from the Lincoln Correctional Center in June.

The Nebraska Department of Correctional Services announced the action Friday in a news release but declined to name the staff members. The release says the discipline involved firing, demotion, suspension and disciplinary probation. No criminal wrongdoing by staffers was found.

The action came after convicted sex offenders Armon Dixon and Timothy Clausen escaped from the Lincoln prison in a laundry truck. Both were recaptured within a week. Director Scott Frakes has said the inmates escaped because staff members failed to follow security procedures.

Criminal charges related to the escape have been filed against Dixon and Clausen, who are now housed at the Tecumseh State Correctional Institution.
