HOULTON — Maine officials have summonsed a Canadian citizen who had a homemade smoke bomb in his car while trying to cross the border at Houlton.

U.S. Customs and Border Protection shut down the border crossing for more than two hours Sunday after a border officer discovered a suspicious device in the trunk of a vehicle. The Maine State Police bomb squad eventually used a water cannon to eliminate any hazard.

Steve McCausland of the Maine Public Safety Department says 22-year-old Trevor Hickerson of Trenton, Ontario, told investigators he made the device in case he got lost in the woods in eastern Canada. He was denied entry and returned to Canada.

Maine’s fire marshal issued a summons for illegal transportation of fireworks. Hickerson also was cited for a small amount of marijuana.
