Police in Providence say they have made 30 arrests as part of a 10-month investigation into opioid drug dealing in Rhode Island and Massachusetts.
Police say six of those arrested as part of "Operation Stop the Flow'' are high-level dealers.
They include 26-year-old Johan Jimenez of Providence, who was identified as the lead supplier of heroin and fentanyl in the city.
He and the others face multiple felony charges.
Jimenez was being held Thursday. It was not immediately clear if he had hired a lawyer who could comment on the charges.
Authorities say city dealers were selling 50 doses of fentanyl for about $120 to lower-level Massachusetts dealers, who would re-sell the drugs at marked-up prices.
Police say more arrests are possible in Rhode Island and Massachusetts.
