SCRANTON - State police said a man from Wayne County was arrested after he attacked two people on an interstate highway, slicing one of them with a box cutter.

Gregory Lee Nicholas Jr., 25, of Beach Lake, faces charges including assault and making terroristic threats. He was placed in the Lackawanna County Prison after failing to post $25,000 bail.

According to state police at Dunmore:

Nicholas flagged down two motorists on Interstate 81 and assaulted them.

The suspect was standing in the interstate around 12:30 a.m., near mile marker 183 between River and Davis streets, when a couple traveling north pulled over.

Nicholas jumped into the back seat and cut the male driver’s face with a box cutter.

Nicholas told the man, “Don’t call anyone or I swear I will cut your throat," according to police.

Nicholas then punched the female passenger, exited the vehicle and went into the southbound lane.

Another motorist, heading south, pulled over after seeing Nicholas in the highway. The suspect unsuccessfully tried to pull the driver from the vehicle.

Local police officers from Scranton and Dunmore arrived and took Nicholas into custody.

What prompted the attack was unclear, but Nicholas told officers that he was intoxicated, according to police.

Nicholas was transferred into the custody of state police. Police did not release the names of the victims.

It was not the suspect's first run-in with the law.

Nicholas was sentenced in September 2014 to spend between one month to one year in the Wayne County Correctional Facility for a charge of possession of a controlled substance-heroin, according to Wayne Independent archives.

That incident occurred on April 10, 2014, in Salem Township.
