The man who allegedly attacked and nearly killed a Suffolk police officer faced new charges Wednesday as more details about the incident were unveiled.

Jonathan Nunez, 25, is accused of stabbing Christopher Racioppo following a traffic stop and foot chase in Patchogue earlier this month.

The stabbing cut major arteries and veins in the officer's leg, causing significant blood loss. A doctor says Racioppo would have died if the artery that was severed had not been controlled within 20 minutes.

Officials hailed the work of a retired NYPD officer and a Marine for helping Racioppo with the suspect and in aiding him before he was taken to a hospital.

Nunez faces 10 charges, including aggravated assault of a police officer and first-degree assault. Nunez's attorney entered a plea of not guilty and Nunez is being held without bail.

It is now known that Nunez has a violent criminal record and was on probation at the time of the alleged attack, officials say. Nunez allegedly was high on methamphetamines at the time of the violent incident and was "extremely combative" with medical staff, Suffolk DA Tim Sini says.

Officials say at the hospital, Nunez kicked another officer in the eye. Doctors ended up having to sedate him.

Hundreds of police officers gathered outside the court Wednesday for Nunez's arraignment in a show of support for Racioppo.

Racioppo was released from a hospital Monday in what's being called a miraculous recovery.

Nunez faces up to 30 years in prison if convicted of the top count.
