Providence Police say they've arrested 30 people in connection with a ten month drug investigation known as "Operation Stop The Flow."

WLNE ABC 6 identifies the alleged ringleader as 26 year old Johan Jimenez of Providence, who is believed to be a major supplier of heroin and fentanyl in Providence and on the Southcoast.

Police say 24 of the 30 arrested were mid-level dealers from Fall River and New Bedford.

Police say the investigation is ongoing, and there are still six active warrants for suspects in Massachusetts that police are trying to track down.
