An Allegheny County man who is not permitted to have a gun is accused of showing another motorist a firearm on Route 22 on Sunday afternoon, according to state police.

Dylan Peter Dunbar, 24, of Hazelwood, allegedly displayed the weapon in Salem Township after an incident with another driver, police said.

Authorities were notified of two vehicles driving erratically on Route 22 westbound at 2:44 p.m. The victim told police the driver of a Chevrolet Silverado, later identified as Dunbar, showed him a handgun while both were traveling on the highway.

Police caught up to Dunbar on Old William Penn Highway in Murrysville. Officers found a loaded handgun in the center console. He did not have a permit to conceal a firearm and a previous felony conviction prohibits him from possessing a gun, police said.

Dunbar is charged with firearms violations and terroristic threats. He was being held at the Westmoreland County Prison on $25,000 bail. A March 18 preliminary hearing is set.

He did not have an attorney listed in online court records.
