PHOENIX (AP) — An Arizona prison teacher who was left alone in a classroom and then raped by a convicted sex offender has filed a $4 million claim against the state Department of Corrections.

The claim filed Thursday comes nearly six months after the attack at the Eyman prison 60 miles south of Phoenix and a week after the state's worker safety agency launched a full review of the state prison system's worker safety practices.

The teacher was alone in a classroom with no guard nearby on Jan. 30 when a convicted rapist assaulted her. Details of the case were first reported by The Associated Press after an open records request.

The claim says the department "failed miserably" in its duty to keep the teacher and other employees safe.
