No charges two months after Vic jail riot

No prisoners have been charged more than two months after Victoria's worst prison riot.

Masked inmates armed with sticks smashed windows, bashed doors and lit fires at the maximum security Melbourne Remand Centre during the June 30 riot, which was triggered by a statewide ban on smoking in prisons. The riot caused more than $10 million worth of damage.

Corrections Victoria Commissioner Jan Shuard says although no one has been charged over their involvement in the riot, she has full confidence that the Victoria Police investigation will bring perpetrators to justice.

Prisoners remain in lockdown at the prison, where 85 per cent of repairs have been completed, and some are applying for reduced sentences because of the long lockdown.

Ms Shuard says time off to compensate for the lockdown, known as emergency management days, is not an entitlement and no application has been approved at this stage.

"No prisoners involved in the riot will be granted emergency management days," she said on Sunday.

Opposition Leader Matthew Guy said the laws allowing prisoners to apply for reduced jail time over prison riots should be scrapped.

He said no prisoners, whether they were involved in the riots or not, should get a sentence reduction.
