Julian Squires has been sentenced to 18 months incarceration for his part in a riot at Her Majesty's Penitentiary in August 2012.

Squires, 26, was sentenced for his involvement in a hostage taking and the destruction of prison property.

During the riot, inmates took control of a cell block and threatened to kill hostages and prison guards.

Inmate involved also smashed windows, flooded floors, and pulled down steel doors and ceiling tiles.

In the end, the rioters traded the sole hostage in exchange for two cigarettes before surrendering to police.

Damage during the riot was estimated at nearly $100,000.

Squires has been in and out of prison for much of his adult life.

He told the court on Monday that he hopes to make a fresh start when he finishes this sentence.

Philip James Hollihan, Justin Owens, Justin Hopkins have all pleaded guilty to mischief.

Fellow inmates Adam Hayden and Justin Wiseman are facing the more serious charge of kidnapping.
