Authorities in New York say they uncovered a massive heroin packaging mill inside of a Bronx apartment and they seized $2million worth of the powerful drug.

Members of the New York Drug Enforcement Task Force (NYDETF) Group T-42 were conducting a surveillance operation near Third Avenue and East 168th Street in the Morrisania neighborhood of the Bronx.

As part of the continuing investigation into narcotics trafficking in New York, the drug task force members observed Wladimir Rosa Reyes exiting an apartment building located at 547 East 168th Street carrying a black suitcase Wednesday.

Reyes put the suitcase into a black Honda Odyssey, and agents began following him as he drove off.

While conducting surveillance in the Bronx, authorities watched Wladimir Rosa Reyes exit a building and load a large black suitcase into his vehicle before driving off. They stopped the vehicle and uncovered 50,000 glassine envelopes of heroin wrapped in brown paper (above)

Authorities seized the heroin and obtained a search warrant for 547 East 168th Street, Apt. 4I. When they entered the apartment, they discovered a heroin mill operation (above) where nine people were in the process of packaging the drug

Of the bust, New York City's Special Narcotics Prosecutor Bridget G. Brennan said: 'This high volume heroin packaging mill was on track to escalate overdose deaths and devastate the lives of those who become addicted and the people who love them'

They stopped his vehicle a short time later and while searching the Honda, agents discovered 50,000 glassine envelopes of heroin wrapped in brown paper inside the large suitcase.

The envelopes were stamped with the brand names 'Magic City' and 'Red Bull'.

Authorities seized the heroin and obtained a search warrant for 547 East 168th Street, Apt. 4I.

When they entered the apartment, they interrupted an 'active large-scale heroin packaging operation with nine individuals in the process of packaging heroin into glassines,' officials said in a press release.

Some of the suspects tried to flee the apartment, but all nine were arrested along with Reyes.

Reyes, Antonio Delorbe Mercedes, Daniel Garcia Mithill, Antonio Delorbe, Gisela Guzman Hernandez, Norlisa Jimenez, Andy Zayas, Osvaldo Monegro, Jose Duarte, Andy Vizzcarondo, Alcibiades Delosantos Mateo are all facing several charges in relation to the heroin mill.

Inside the apartment, authorities seized nearly five pounds of powdered heroin, thousands of filled glassine envelopes and an undisclosed amount of cash.

Photos of the scene show several tables with the necessary drug packaging materials, including grinders, cutting agents and empty glassine envelopes.

One photo in particular shows the stamps used to brand the envelopes of heroin with specific names, including Stop Snitching, Red Bull, Dope, Overdose, King Kong and Extra Cheese.

Of the arrests and seizure, New York City's Special Narcotics Prosecutor Bridget G. Brennan said: 'This high volume heroin packaging mill was on track to escalate overdose deaths and devastate the lives of those who become addicted and the people who love them.

'I thank our partners in law enforcement for their commitment to reducing the supply of heroin which is overwhelming our city and surrounding areas.

'The single most important thing we can do to rein in this epidemic is reduce the flow of addictive drugs available in our neighborhoods and on our streets.'

Suffolk County District Attorney Thomas Spota added: 'The trafficking organizations at the foundation of the heroin and opioid epidemic are being targeted by law enforcement working together to aggressively find, investigate and ultimately dismantle their operations.

'Our partnerships in law enforcement ensured a successful outcome in this case.'

Last year, there were more than 1,300 fatal drug overdoses in New York City alone.
