OMAHA, Neb. (AP) — State prison officials say a Nebraska Department of Correctional Services caseworker has been arrested for allegedly having a sexual relationship with an inmate.

Local media says 27-year-old Elizabeth Blake faces charges of sexual abuse/sexual assault of an inmate and prohibited acts of a correctional employee.

The department says it learned about a possible sexual contact between Blake and an inmate. Authorities say an investigation resulted in Blake’s arrest and resignation.

Blake was a unit caseworker at the Community Corrections Center in Omaha. She started with the department in November.

Blake’s case is not on the state’s online court system, and it’s unclear if she has an attorney.
