INDIANAPOLIS (AP) — Indiana’s contract with a Florida-based company that runs prisons across the nation requires it to reimburse the state for the costs police incurred subduing Tuesday’s riot at an eastern Indiana prison it manages.

State prisons chief J. David Donahue said Wednesday that staff at the New Castle Correctional Facility are assessing the emergency response costs and damage to the prison following the riot, which slightly injured two staff members and seven prisoners.

Donahue, the commissioner of the Indiana Department of Correction, said “it would be total speculation” to estimate the riot’s costs at this time.

Trina Randall, a spokeswoman for GEO Group Inc., said it could take a few days to assess the expense of sending emergency squads, county police and Indiana State Police to the prison to end the fracas, which involved about 500 inmates from Arizona and Indiana.

“They’re going from housing unit to housing unit today doing that estimate. We’re responsible for the costs of the riot, and I’m assuming that includes overtime,” she said.

During Tuesday’s riot, prisoners from Arizona and some from Indiana set mattresses and paper afire in a prison courtyard, destroyed furniture and broke windows, officials said.

Boca Raton, Fla.-based GEO Group assumed management of the medium-security prison about 45 miles east of Indianapolis in January 2006 under the terms of an earlier contract.

Last month, the Indiana DOC and GEO Group signed a contract specifying how the company would handle inmates Indiana had agreed to accept from Arizona. As of Wednesday, about 630 Arizona inmates had been moved to the prison.

The remaining transfers to the prison, which already houses 1,050 Indiana prisoners, have been temporarily halted.

Under that deal, Indiana agreed to pay GEO Group at least $314,212 per week for housing up to 1,200 inmates from the Western state.

Last month, Indiana signed a contract with the Arizona Department of Corrections under which Arizona agreed to send up to 1,260 inmates to Indiana. Arizona officials agreed to pay their Indiana counterparts at least $536,256 per week for housing up to about 1,200 Arizona inmates.

Indiana House Speaker Patrick Bauer, D-South Bend, said Wednesday that the state should cancel that contract. He said Arizona officials knew the arrangement was problematic before the riot and were aware that Indiana bans smoking in prisons, while Arizona permits it. Randall has said many prisoners were upset by the policy, which might have contributed to the disturbance.

“They’re not our prisoners; they’re Arizona’s prisoners. They ought to be sent back,” Bauer said.

Earl Goode, the chief of staff for Gov. Mitch Daniels, released a statement urging Bauer to stay focused on working to complete a new state budget before the current legislative session ends Sunday.

“It would be best for all Hoosiers if the Speaker stayed on task and let Commissioner Donahue continue to run the Department of Correction,” Goode said in his statement.
