CHARLESTON, Maine (AP) — A Dover-Foxcroft man has been arrested on drug charges after police found what they say were chemicals used in the manufacture of methamphetamine in the pickup truck he was driving.

The Maine Drug Enforcement Agency says 33-year-old Joel Frigon had been under investigation for several weeks after police were told he had the chemicals.

He was pulled over on Route 11 in Charleston on Wednesday.

The pickup was towed to Bangor, where chemists from Maine’s Health and Environmental Testing Lab searched it and allegedly found evidence that indicated that Frigon intended to, or was involved in, the manufacture of methamphetamine.

Frigon is charged with trafficking in methamphetamine.
