PELHAM - A Massachusetts man was trapped inside his car Sunday night after he crashed into a utility pole, snapping it in two and sending live wires across his car and Nashua Road.

Police said Robert McGaw, 28, of Chelmsford, was drunk when he crashed his car at 10:15 p.m. near 76 Nashua Road.

A crew from Liberty Utilities went to the scene to shut the power off so McGaw, who was conscious and talking through his open window to emergency personnel, could safely exit his car.

Police said an initial investigation showed McGaw was traveling east on Nashua Road in his gray 2001 Infiniti sedan when he went off the shoulder of the road and crashed into the pole.

McGaw was taken by ambulance to Southern New Hampshire Regional Medical Center where he was treated for minor injuries.

He was later arrested and charged with driving while intoxicated.

What's next: McGaw is to be arraigned March 11 in 10th Circuit Court, Salem District Division.
