A prison escapee has been arrested after nearly nine months on the run.

Selim Sensoy had been hiding out in a home in Windsor and was arrested yesterday.

The 45-year-old escaped a minimum-security prison at Glen Innes last May and stole a tractor to make his getaway.

He was serving a three-year sentence for assaulting his sister and possessing a firearm.

Sensoy remains a person of interest in his mother's disappearance.

Nadire Sensoy hasn't been seen since December 2018 and in June last year her family made an emotional plea for information.

Police have offered a $350,000 reward for information.

Neighbours said they'd seen Sensoy at the Windsor home in recent months but only knew him as Tony and had no idea he was a wanted man.

He pleaded guilty to escaping custody and stealing a motor vehicle and will remain behind bars until 2023.
