More than 20 prisoners have been charged with taking part in the riot at Greenough Regional Prison that lead to the biggest breakout in WA history.
In July inmates at the regional facility near Geraldton used petrol, angle grinders and axes to cause mayhem before 10 prisoners made a break for freedom.
The riot caused $2 million damage while the escape sparked a large scale manhunt that ended two days later.
On Friday detectives from the major crime squad charged 23 men and one woman with causing damage by fire.
If found guilty, the prisoners could face up 14 more years in jail as well as being slugged with part of the damage bill.
All 24 will face the Perth Magistrate’s Court on October 30.
In July WA Prison Officers Union Paul Ledingham said damaged parts of the facility would not hold prisoners for up to a year.
“It could be be nine to 12 months at least before Greenough is fully operational again,” he told 7 News Perth.
“It’s utter devastation. We’ve seen staff control rooms – supposedly secure areas for staff – smashed, destroyed and in one case burnt, fully burnt out.”
