CHELMSFORD — A federal agent drove the vehicle from upstate New York before an informant got behind the wheel to finish the trip to a restaurant parking lot off Route 38 in Tewksbury.
The informant had been asked to deliver the 108 pounds of marijuana that was in the vehicle, but called agents with the U.S. Immigration and Customs Service to let them know about the drug deal ahead of time.
