Inmates Robert Wright, Jimmy Loughnan, Arthur Gallagher, David McGauley and Ricky Morris - from one side of the unit - and Craig 'Slim' Minogue and three other inmates on the other side sealed off their section doors with a tennis net. Mattresses and other bedding were then stacked against the doors and set on fire. They covered windows in the day room with paper so the prison officers could not see which prisoners caused the damage.
