WHATELY - A Chicopee man was arrested on drunken driving and other charges Tuesday after state police spotted him driving through a construction zone on Interstate 91 at 105 mph, or 60 mph above the posted speed limit.

State police report that when troopers caught up to and stopped the truck in Northampton, they found driver Alexander Shanwenda, 24, was not wearing any clothes.

Shanwanda was charged with operating under the influence of alcohol, driving to endanger, marked lanes violation and speeding through a construction zone.

According to police, Trooper Michael Tucker was patrolling I-91 South when he was alerted by the Northampton barracks of reports of a black pickup truck on I-91 driving erratically and at a high rate of speed.

Tucker spotted a vehicle matching that description and saw it change lanes suddenly without signalling, nearly causing a collision with a box truck, police said.

The truck then sped up through a construction zone. Tucker clocked it driving 105 mph, police said. The speed limit in the construction zone has been reduced to 45 mph.

The truck eventually slowed down due to traffic in Northampton, and Tucker was able to make a vehicle stop.

When Tucker approached the vehicle he saw that Shanwenda was naked and trying to cover himself up with a pair of pants on his lap, police said. Tucker could also detect the presence of alcohol and could see an empty bottle in the back of the truck.

Shanwenda was made to put on his pants and then put through a series of roadside sobriety tests, police said. When he failed them, he was placed in custody and taken to the Northampton barracks for booking.

Troopers searched the truck and found what was left of two six-packs of beer. Five of the bottles were unopened, three were empty, and four were missing.

Shanwenda is scheduled to be arraigned in Holyoke District Court.
