The inmates at the justice centre in Parkville climbed on its roof while wielding metal bars around 2.30pm, a Victoria police spokeswoman told journalists.
The unruly group then began to smash windows, swing from the roof, kick in sheets of glass, and rip air conditioning units to shreds with their hands, according to Nine News.
Just before 10pm, the group voluntarily surrendered to the heavily armed officers at the scene.
The group began to immediately smash windows with their poles, fists and feet

Police wearing heavy armour and shields and the Department of Human Services search team negotiated with the juveniles until they agreed to step down, police said.
It is the second time in less than six months a group of inmates has climbed onto the roof, according to Nine News.
Last October, six people climbed onto the green roof with tennis rackets.
