Lt. Jose Briones says a staffer spotted the animal at about 2 a.m. Tuesday on the roof of the special offenders unit of the Monroe Corrections Complex. He says the animal must have climbed a fence or pushed in through some gap in the fence.
The prison called state Fish and Wildlife officers, who are trying to remove the animal, possibly with a tranquilizer gun.
Briones says raccoons have been seen outside the fence before but he knows of no other animals breaking inside.
