LEWISTON – A truck driver suffered minor injuries early Tuesday when a rock was dropped from an overpass and through the windshield of his rig.

Police went to the area of Old Lisbon and Webster roads about 1 a.m. after two truckers reported that their vehicles had been struck by heavy objects from above.

“We checked the area but didn’t find anything other than a rock on the overpass,” said police Sgt. David St. Pierre.

Both truckers pulled into the service area at Mile 81 on the Maine Turnpike after their rigs were struck just minutes apart.

Lewiston and Maine state police searched the area where the rocks were believed to have been dropped or thrown. No suspects were found and no arrests had been made by late Tuesday.

Police said a rock smashed through the windshield of one of the tractor-trailers, injuring the driver inside. The driver did not require hospital treatment and his name was not immediately available.

Maine Turnpike Authority officials contacted police about 1:15 a.m. after learning about the back-to-back incidents.

State police were continuing to investigate the matter Tuesday. State police and Lewiston police investigators fear that more serious injuries will result from similar incidents.

Over the weekend, two teens in Dover, N.H., were arrested for allegedly dropping rocks from an overpass in that city. According to investigators, the 17-year-olds admitted they dropped rocks onto five vehicles and videotaped it as it happened.

Police said the teens were apparently inspired by the MTV television show “Jackass,” an internationally popular show that showcases dangerous stunts and pranks.

Nobody was hurt in the Dover spree. The teens were charged with criminal mischief and reckless conduct.

On Tuesday, police here said those responsible for the incidents at the Old Lisbon Road overpass could face similar charges. Investigators are trying to determine if the incidents early Tuesday are related to similar ones in the area over the past six months.

Police also point out that several drivers or passengers have been killed around the country from items dropped from overpasses in recent years. Two teens in Omaha, Neb., pleaded guilty to manslaughter this year in the death of a 34-year-old man killed when a brick was dropped onto his car last summer.

In May, in a case that made national headlines, a Tennessee woman traveling with her family after attending a graduation in West Virginia was killed when a rock was dropped from an interstate overpass. Four young men were arrested in connection with the death of the 69-year-old.

Anyone with information about the Tuesday night incidents in Lewiston is asked to call Maine state police at 1-800-482-0730.
