FALL RIVER — Two Fall River residents have been arrested on numerous drug charges after police are tipped off to a transaction involving Fentanyl.

Fall River Police received information on Monday that Joan Rezendes, 58, and Paul Chasse, 23, both of Fall River, would be returning to the city in a brown Hyundai after purchasing a large amount of Fentanyl.

Fall River Police detectives later observed the vehicle exiting the Hartwell Street off-ramp. Police stopped the vehicle on Hartwell Street.

During the investigation, Chasse, who was a passenger in the vehicle, allegedly admitted to police that he had obtained five bricks of Fentanyl, and over three bricks were stored in his underwear. A brick of Fentanyl is equivalent to fifty bags.

Rezendes, who was driving the car, allegedly told police that she had snorted the bags of Fentanyl that she had received from Chasse as payment for driving him and she had no more Fentanyl on her or in her car. Police searched the vehicle and found 60 bags of Fentanyl in Rezendes' purse.

180 bags of Fentanyl were found in Chasse's possession.

Rezendes and Chasse were arrested and charged with possession with intent to distribute a Class A substance and conspiracy to violate drug laws.
