At least four correction officers and several inmates were hurt in a late night fight at Rikers Island.
A Department of Correction spokesperson tells NY1 that the fight broke out Friday night in a high-custody housing unit at the George R. Vierno Center.
Sources say that the correction officers were treated for exposure to a chemical agent, but they did not say what the chemical was.
Several inmates also suffered minor injuries.
Officials could not say what started the fight.
