A convicted rapist from central New York who removed his GPS ankle bracelet and stopped reporting to his parole officer has been seen in Pennsylvania. 

Thomas Mailey, a spokesman for the state Department of Corrections and Community Supervision, said that Ronald Cook, 66, was last seen at around 12:30 p.m. Friday in Scranton, Pennsylvania. He was wearing a dark jacket at the time he was spotted. 

The state issued an alert after Cook removed his ankle bracelet and didn't report to his parole officer. Before he was observed in Scranton, he was last seen wearing a bright yellow windbreaker at 3 p.m. Wednesday in Rome. 

Cook, a white male, stands 5 feet 9 inches tall and weighs 240 pounds. He has gray hair and hazel eyes. 

In 1991, Cook was convicted of first-degree rape after sexually assaulting a 24-year-old woman in Binghamton. He was sentenced to up to 25 years in state prison. He was released from prison in 2012. 

Due to his crime, Cook registered as a sex offender. He is a Level 3 sex offender, which means he's at a high risk of committing another offense. 

Cook should be considered dangerous. If you see him, call 911.
