Border officials at the Ambassador Bridge say they found what they think is cocaine in a vehicle re-entering the country.
Two Windsor residents, a father and a son, were in the vehicle headed back home last Sunday after spending the day with family in Michigan.
Their vehicle was sent to secondary inspection when the Canada Border Services Agency says it found seven bricks, or 8 kg, of suspected cocaine in the engine compartment.
The driver was arrested and taken into custody by the RCMP.
