A TEENAGER who's had a "terrible life" has been sentenced to imprisonment for causing more than $17,000 damage to a detention centre.
The 18-year-old, who is serving a sentence in Ashley Youth Detention Centre for armed robbery, trashed the Deloraine facility in January.
Angry at being disciplined the teenager, along with four others, climbed on to the roof of the centre.
They removed air conditioners, exhaust fans, roofing and an Austar satellite dish and threw the items off the roof.
The building was unusable for two weeks.
The offender, who pleaded guilty to unlawfully destroying property, caused most of the damage.
Yesterday Chief Justice Alan Blow heard the defendant had left school in year 8 and had a troubled upbringing, involving significant periods in child protection.
"So far you have had a terrible life. You have been treated very badly," Justice Blow said.
Justice Blow sentenced him to five months' imprisonment, cumulative to his other sentences and ordered he pay $17,300 in compensation.
