A Pittsfield man has pleaded guilty to aggravated assault and resisting arrest stemming from a warrant arrest in early December.

Jessie J. Greenhalgh entered the plea before President Judge Maureen Skerda on Thursday.

Charges of disarming law enforcement officer, obstructing the administration of law or other governmental function, simple assault, driving while under suspension and false identification to law enforcement officer were not prosecuted.

He had initially been charged with first-degree felony aggravated assault but First Assistant District Attorney Cody Brown said he spoke with the officers who were “completely fine” with offering second-degree aggravated assault as a plea offer instead.

Pennsylvania State Police made contact with Greenhalgh on Dec. 1 at approximately 2:15 a.m. on Poplar Street between Third Ave. and Fourth Ave. in Warren, police alleged at the time, noting that Greenhalgh was wanted on an arrest warrant.

Greenhalgh gave troopers a false name and date of birth and fought with troopers while being taken into custody.

Troopers fired a taser several times and used pepper spray during a physical effort to subdue him, according to the police report.

Greenhalgh was taken into custody and transported by ambulance to Warren General Hospital for treatment of injuries and observation, police said.

In reading the specifics of the charge to Greenhalgh, Skerda noted that both officers were injured in the altercation.
