Eleven individuals were arrested on Thursday and Friday and ordered detained on drug and firearms charges resulting from an eight-month federal law enforcement investigation into the trafficking of heroin into Rhode Island by an alleged Dominican organization with ties to Mexican drug cartels.

The investigation is continuing.

The investigation by the United States Attorney’s Office, the FBI, and the DEA, along with the Rhode Island State Police and local law enforcement detectives assigned to the task forces, resulted in the execution of federal search warrants and arrest warrants in Providence, Cranston, North Providence, Pawtucket, and West Warwick, Rhode Island. In addition to the arrests, federal agents and state and local detectives seized more than three kilos of heroin, approximately 200 grams of cocaine, approximately $450,000 in cash, a substantial quantity of high-end jewelry, five firearms (four of them loaded), and 12 vehicles.

Four of the individuals were arrested on Thursday at a West Warwick residence where agents seized approximately $300,000 in cash, more than two kilos of heroin, nearly ¼ kilo of cocaine, four vehicles, and a substantial quantity of high-end jewelry.

The investigation, arrests, and seizures were announced by United States Attorney Peter F. Neronha; Richard DesLauriers, Special Agent in Charge of the FBI’s Boston Field Office; and Kevin L. Lane, Acting Special Agent in Charge of the New England Field Division of the DEA.
