Clinton Correctional Facility in Dannemora, New York is on full lockdown today following disturbances Thursday night.
The New York State Department of Corrections says the lockdown is the result of an incident that occurred in the prison yard involving many inmates Thursday night.
A number of chemical agents and a warning shot were fired after orders by guards were ignored.
The Plattsburgh Press Republican reports it began as a fight between four inmates and a second brawl occurred as inmates were brought inside.
One staff member was transported to a local hospital with minor injuries.
The incident is being investigated by the Department of Corrections’ Office of Special Investigations.
