Five charged over SA prison damage

Five prisoners have been charged with property damage after allegedly climbing on the roof of a South Australian jail.

Police allege the men climbed on the roof of a building at Port Augusta Prison on March 15 and 16, and then caused extensive damage to windows and air conditioning units.

Four were arrested on Thursday and one was arrested on Friday, after an investigation.

Most of the men reside at Port Augusta, but one is from Yatala Prison.

The group, aged between 19 to 52, have all been charged with property damage. They are due to appear in the Port Augusta Magistrates Court on April 27.
