FAIRBANKS, Alaska (AP) - Authorities are investigating an incident at a prison in one of Alaska's largest cities that a state corrections spokeswoman says resulted in minor damages to the facility.
           
The Fairbanks Daily News-Miner reports local police and the Alaska State Troopers set up a perimeter outside of the Fairbanks Correctional Center Thursday in Fairbanks.

Troopers said in an online dispatch that about 15 inmates had occupied part of the facility after a riot. Members of troopers’ Special Emergency Reaction Team responded.

“Numerous requests for the inmates to surrender were made,” troopers wrote. “The inmates responded to those requests by breaking windows in the facility as well as pouring soap and water on the floors. Members of SERT, supported (by) officers from the correctional facility, deployed chemical irritants. As a result of the chemical irritants being introduced, the inmates surrendered without further incident.”

Troopers Capt. Ron Wall says authorities plan to file numerous charges -- described by the dispatch as felony assault and riot -- stemming from the disturbance in one of the prison's wings. He says the facility was not breached.
           
Department of Corrections spokeswoman Megan Edge said there was an attempt to create a disturbance that a department emergency response team was able to get under control with support from troopers.          

Edge told The Associated Press there were no injuries to inmates or staff.
