Authorities in New York state have made a record drug bust, seizing 33 kilograms of heroin and two kilograms of fentanyl and indicting 25 people, including some living in Pennsylvania and New Jersey.

Attorney General Eric Schneiderman and the New York State Police announced the action Friday, unsealing a 98-count indictment. Schneiderman's office said the seizure is the largest ever in the 46-year history of New York's Organized Crime Task Force.

The bust also seized 300 grams of cocaine, two semi-automatic handguns and eight vehicles.

The investigation was called "Operation Dirty Dope" and led to the disruption of what Schneiderman's office said was a sophisticated distribution ring that moved most of the drugs from Mexico into Tucson, Arizona.

From there, the drugs were moved in hidden compartments in cars from Arizona to the Bronx, Washington Heights and Pennsylvania, Schneiderman said. Traffickers, he said, then moved the drugs to sell in Suffolk County, New York, and the central Massachusetts town of Leominster.

"Operation Dirty Dope is another step in our multi-faceted effort to curb the heroin crisis that is destroying our communities," Schneiderman said. "Our message to dealers and traffickers is simple: we will not tolerate anyone smuggling death into our state."

Twenty-five individuals living in New York, Massachusetts, Pennsylvania, Arizona and New Jersey have been indicted in connection with the case.
