The Royal Newfoundland Constabulary announced Wednesday the details of a drug trafficking bust that turned up 500 grams of the deadly synthetic opioid.

More than a dozen people were arrested and a "record-breaking" quantity of fentanyl seized across several states in a blow to one of the largest and "most dangerous" drug cartels in America, authorities say.

This historic drug seizure … is a significant blow against the Sinaloa Cartel that removes poison from our streets,' Bondi says.
