Police have charged dozens of youth offenders with more than 150 offences following January's riot and breakout at Victoria's Malmsbury Youth Justice Centre.
About 30 inmates were involved in the uprising, with 15 of them then escaping after assaulting a staff member and stealing a security pass.
Eight were captured before nightfall, while the other seven were alleged to have armed themselves with a knife and a baseball bat and committed four armed robberies in Noble Park, Bonbeach and Moe.
The last two inmates were on the run for 24 hours before being arrested.
Police said on Friday night the Fugitive Taskforce was co-ordinating a "large and complex investigation supported by regional investigators who are dealing with incidents that occurred in a number of locations".
