Three Attica Correctional Facility guards were injured in an outbreak of violence Wednesday, according to the union representing corrections officers.

One corrections officer suffered multiple facial injuries and a concussion, and remains hospitalized in Erie County Medical Center; two other officers who came to the aid of their fellow officer were treated for injuries and released, the union said.

State police who are conducting an investigation said the inmate who triggered the outburst may be charged.

According to the New York State Correctional Officers and Police Benevolent Association, the incident began when an inmate responded to a “routine verbal inquiry” of a guard by punching him in the face – causing three fractures and a concussion. A second officer was bitten on his right forearm, and a third officer suffered a knee injury.

The officer who was bitten was treated in ECMC and the other guard in United Memorial Medical Center, Batavia.

Donn Rowe, president of the union for correctional officers, Thursday faulted Gov. Andrew M. Cuomo and the Department of Corrections and Community Supervision for overcrowding at Attica – an “irresponsible approach to managing the budget of this public safety agency.”

“The state wants to create the illusion that the system is rife with empty beds, but this is only made possible by double-bunking inmates,” Rowe said.

“Instead of taking the opportunity to right-size the system, and make it safer for correction officers and inmates, the state continues to warehouse inmates by double-bunking and maintaining crowded and understaffed facilities.”

Thomas W. Mailey, spokesman for the state Department of Corrections and Community Supervision, said late Thursday that the department does not comment on ongoing investigations.
