OLD LYME, Conn. — Connecticut State Police say they seized 2.2 pounds of the powerful opioid fentanyl with a street value of $1 million during a traffic stop.

Police discovered the narcotics during a stop on Interstate 95 in Old Lyme on Wednesday. Officials say they stopped the car because they received information that it contained illegal narcotics.

Police say the 26-year-old driver and his 28-year-old passenger, both of Providence, Rhode Island, consented to a vehicle search. Officers say they found the drugs in the car with the help of a police dog.

Gabri Darlin Javier-Delapaz and Alcides Rafael Gomez-Alba were charged with possession and are currently in custody. They are scheduled to appear in Superior Court in New London on Thursday. It’s not clear if they have lawyers.
