Fears Vic prisoners may riot again

Prison officials are on high alert with fears another major riot may take place at a Melbourne jail, while others are worried prisoners may have access to their personal details.

Tensions remain high at the Metropolitan Remand Centre following the June 30 and July 1 riots over a smoking ban, which left a $12 million trial of destruction.

Most prisoners are on 23-hour lockdown, as repairs to smashed doors, walls, fences and the fire alarm and heating systems continue.

Rioting prisoners who broke into staff areas took some records. But Victorian Corrections Minister Wade Noonan has refused to confirm those records included guards' addresses and other personal details.

Some staff were receiving "psychological assistance" following the riots, Mr Noonan said.

Management at the Ravenhall prison, in Melbourne's outer-west, was treading lightly, and some staff had taken stress leave since the riots, he said.

"There is some tension out there and Corrections Victoria will be very cautious in their approach going forward," Mr Noonan told 3AW on Friday.

A review to be completed next month is examining the state's preparedness for the riot and the responses to it from Corrections Victoria and police, firefighters and paramedics.

The state opposition says the review should also look at the government's handling of the smoking ban.

"We have been told by a number of sources that it was well known trouble was coming," Mr Guy told reporters on Friday.

Mr Guy also baulked at suggestions the damage bill was between $10-12 million, saying he heard the figure was much closer to $20 million.
