BOSTON (CBS) -- A serious case of road rage has led to the arrest of a Fall River man.

State Police received a 911 call around 3:30 p.m. Sunday about a man driving a Kia Forte who pulled out a gun and pointed it at another driver on I-93 in Boston.

A short time later, troopers arrested 64-year-old Gary Moniz on the southbound side of the highway just before exit 15.

Police say officers found a loaded 9 mm Beretta handgun in Moniz's car.  He did not have a license to carry a gun in Massachusetts.

He's charged with assault with a dangerous weapon, unlawful possession of a firearm without a license, and unlawful possession of ammunition without a permit.

Moniz is scheduled to appear in Dorchester District Court Monday.
