HOULTON, Maine — The driver of a vehicle with a placard indicating an explosive device was on board led Maine State Police on a pursuit along Interstate 95 to the Canadian border Monday, authorities said.

A police officer fired shots after the motorist tried to maneuver the truck toward the Canadian port of entry in Woodstock, New Brunswick, and the man surrendered without injury, state police said.

The border crossing was temporarily closed and crime scene technicians and the Maine State Police Bomb Squad were expected to be on scene overnight, authorities said.

Authorities said there was no danger to the public.

A state trooper noticed the sign on the vehicle indicating the motorist had some type of explosive device after attempting to stop the motorist around 10:40 a.m. Monday.

Tony Holford, 42, of Providence, Rhode Island, was charged with aggravated reckless conduct, terrorizing and failure to stop, state police said.

State police said the man was taken to the Aroostook County Jail. It was not known if he had a lawyer.

Maine state police, the state attorney general’s office and Canadian authorities were jointly investigating the incident, authorities said.
