WICHITA, Kan. (AP) — A former agent with U.S. Immigration and Customs Enforcement has pleaded guilty to helping an inmate try to escape from a Kansas jail by impersonating an immigration officer.

Forty-two-year-old Andrew Pleviak pleaded guilty Wednesday in Kingman County District Court to making false information and attempted aiding of escape. He’s also charged in federal court with false impersonation of a federal officer.

Prosecutors say he falsely identified himself as an ICE agent in a foiled attempt last month to free an inmate held at the Kingman County jail, about 45 miles (72 kilometers) west of Wichita. He allegedly provided a sheriff’s deputy a memorandum on ICE letterhead falsely claiming the inmate was an important confidential informant and saying ICE would drop the detainer on him.

Sentencing is set for Nov. 20.
