The California Department of Corrections and Rehabilitation now says 150 inmates were involved in Wednesday's riot at the New Folsom Prison and that 11 of those inmates had to be hospitalized. One had been shot.
The department's Dana Toyama says the men in the maximum security, "C" Facility are no longer on lockdown, but their movements are restricted while state and prison officials conduct interviews and collect evidence.
TOYAMA: "The prison's investigative services unit actually investigates the cause of the riot -interview inmates, crisis response teams determine if there's possibility of any future conflict in the immediate future as well as what caused the actual riot and who started it.
There is also an investigation into the use of lethal force.
Corrections now says no prison staff were injured during the riot. One person was treated for an unrelated reason.
