A 19-year-old will spend another few months behind bars for causing a riot at the Banksia Hill Juvenile Detention Centre.
The man faced Bunbury Magistrates Court on Thursday, January 24 for sentencing, via video link from Acacia Prison.
He had admitted to five counts of aggravated burglary, five of criminal damage/destruction of property, two of stealing, one of trespassing, and one of being armed/pretending to be armed to cause fear.
Police prosecutor Sergeant Jo Morrissey told the court he and several others were involved in an incident on May 5, 2017.
The man and a co-accused instigated a riot at the facility.
After climbing onto the roof, the pair broke off antennas and pipes to use as weapons.
They damaged several rooms, before using an angle grinder to free an inmate.
The accused and co-accused then stole numerous tools from workshops and sheds on the premises.
They also caused a scrub fire and graffiti damage.
The inmates damaged roof panels, sky lights, walls, and approximately 188 windows.
Overall, the riot caused $1.3 million in damages.
The man’s lawyer said his client was party to less than half the overall damage bill ($500,000).
The defence revealed the man was already serving a four-year, three-month sentence.
Sgt Morrissey described the 19-year-old’s actions as “unacceptable”.
Magistrate Belinda Coleman said the man still had the potential to lead a normal life after prison.
The 19-year-old will serve another six months on top of his current sentence. The man was made eligible for parole.
