Officials say four corrections officers were attacked by an inmate on Rikers Island Friday.

The Correction Officers Benevolent Association says there was an "unprovoked attack" by an alleged Bloods gang member.

It says one officer had a concussion and a broken nose, and the three officers who came to help suffered a broken finger and sprained wrists.

The president of COBA responded to the attack saying, "This incident is just one of the countless assaults on our correction officers that have occurred recently. Assaults on our officers are up 15% this year."

News 12 is told the officers were treated at the hospital and released.

In a statement, the Department of Corrections press secretary said, “Any act of violence towards our officers, who work hard to keep our city safe, is not tolerated. This individual will be rearrested.”
