Police issued an urgent message Thursday evening as they search for a man who escaped from the Mountain View Correctional Facility in Charleston.

Arnold Freeman Nash, 65, was convicted in 1992 of robbery and murder in Hancock County. He was sentenced to 45 years in prison.

He escaped the northern Maine facility at 8:37 p.m. Thursday.  He was last seen in the minimum-security unit of the facility and is still believed to be local to the area, according to police.

He is described as 5'6" tall and 160 pounds with blue eyes and sandy hair. He was last seen wearing blue jeans, a white t-shirt and a blue shirt.

Police warn people not to approach Nash. People are asked to contact law enforcement immediately.

This is not the first time Nash has escaped custody. According to the Bangor Daily News, Nash, who was serving a sentence for burglary, and another inmate walked away from a Maine State Prison work detail in July of 1981. They were captured about three weeks later.

Nash was subsequently convicted in 1992 of the murder and robbery of a North Sullivan man,  Wilfred "Willie" Gibeault. He was scheduled to be released in December 2019.

We will bring your more details when they become available.
