Although a high security prison, there have been some significant prisoner escapes. Four prisoners escaped in 1930, and lead the police on a car chase with whom they were involved in a shootout. After escaping into school grounds they were recaptured, with two of the police injured. Six prisoners escaped from the jail in 1979 after an attempted mass break-out by thirty. A wall that was under repair and covered in scaffolding was used as part of the escape, but all six escapees were soon recaptured. There was poor morale amongst inmates in the 1980s leading to a major prison riot. Sixty prisoners went on a rampage on 22 March 1983, and lit fires, destroying the roof of A division. The government saw this as an opportunity to restructure Yatala, rather than simply repairing the damage, and on 21 December announced that A division would be demolished. The former Enfield Council strongly objected due to the building's historic value but demolition began on 6 February 1984.
