Man impersonated federal agent on 2007 flight from Logan

By Globe Staff

The man in his late 40s flashed a badge, said he was a Department of Homeland Security agent, and filled out a flying-while-armed form at the airline ticket counter at Logan International Airport. Then he bypassed security and boarded a plane to San Diego.

On his return trip to Logan several days later, he again told airline personnel he was an agent flying armed and was invited by the pilots into the cockpit, where they told him who the air marshals were on the flight and who else was flying armed.

There was just one problem: The man was an imposter. Stephen Grant, 48, of Rockland was sentenced today to two years of probation on one count of impersonating a federal agent, federal prosecutors said.
