Several terrified staff have been locked inside the facility for their own protection, as police dressed in full riot gear and members of the Youth Justice Safety Emergency Response Team attempt to regain control.
A police car was rammed during the escape, according to media reports.
There were 13 youths who initially escaped by stealing a ute and ramming a fence at the detention centre.
The Malmsbury escapees reportedly smashed into a civilian car on the Calder Freeway.
Police described the young driver as being "out of control" at high speed, according to Seven News.

The escapees reportedly dumped the ute, then carjacked two cars.
There were separate pursuits under way at speeds of up to 150km/h, according to Seven reporter Paul Dowsley.

One car is believed to be travelling towards Melbourne while another is heading to Bendigo.
Police reportedly abandoned one high-speed pursuit after an allegedly stolen car started driving on the wrong side of the road on the Calder.
It has now reportedly driven back on to the right side of the road, heading south.
It is believed police no longer know the location of the two car-jacked vehicles.
There are reports that one staff member at Malmsbury has been injured during the riot.
Teenagers from the Monash and Latrobe units were involved.
The original stolen ute has been found abandoned.
Seven youths are still at large.
Six escaped youths were recaptured and there were five who stayed on the roof, but they later agreed to come down, according to reports.

The latest events come less than two weeks since police were forced to storm the centre after six inmates armed themselves in a secure unit. Four of those offenders have since been remanded into the adult prison system.
On Wednesday, Fairfax Media revealed that the Andrews government was warned in an explosive secret report months before the latest riots in Victoria's youth prisons that the system was spiralling out of control in "a continued and ongoing threat to the safety of staff and clients".
Fairfax Media can also reveal that the man who ran the Parkville and Malmsbury youth justice facilities, Ian Lanyon, has recently been moved from his post, leaving an acting director in his place.
Fairfax was unable to reach him for comment.
