STATEN ISLAND, N.Y. -  More than a dozen people have been arrested, including the alleged supplier of four narcotics-trafficking rings, in what is being called one of the largest drug take downs in Staten Island history.

Officials say the defendants dealt heroin, Fentanyl, cocaine and Oxycodone across the borough for years.

They face conspiracy, drug, and weapons charges.

The main target of the investigation, Damien Rice, has allegedly been selling drugs for decades and is a reputed member of the bloods gang.

"In this case, Mr. Rice is alleged to have served as the head of his own drug organization, while also acting as the main supplier to three separate rings operating here in Staten Island," said Michael Mcmahon, Staten Island District Attorney. "He acted as both a retailer and a wholesaler, providing heroin, Fentanyl, cocaine and pills to three other rings in addition to his own."

Rice was arraigned Wednesday and pleaded not guilty.

The Overdose Task Force says the group was responsible for at least 21 drug overdoses and 8 deaths in the borough.
