Ace Hi

"Police say a 21-year-old Portland man used a blue portable strobe light to pull over a car on Forest Avenue, then pulled a shotgun when approached by the off-duty federal agent he had stopped.

Andrew J. Chaisson faces charges of impersonating an officer and criminal threatening with a gun following the 11 p.m. incident Monday.

The federal agent told police a man in a black 2007 Chevrolet pickup activated a blue strobe light and pulled him over on Outer Forest Avenue.

The truck then backed into a driveway, squealing its tires. The agent became suspicious and was approaching the truck on foot, when the driver threatened him with a shotgun, police said.

The suspect fled in the truck but the agent got the license plate number, a vanity plate 'ACE HI.'

Police went to Chaisson's home where he was arrested and a shotgun was confiscated, police said."
