An alleged drug trafficker is accused of flooding the city with large amounts of fentanyl from Mexico.
Prosecutors say Francisco Quiroz-Zamora was arrested in a sting operation late last year when he showed up to collect money from an undercover officer, following an investigation by the Drug Enforcement Administration.
Investigators say he's linked to more than 44 pounds of fentanyl seized last year at a Bronx hotel, and a Manhattan apartment that was used as a stash house.
The arraignment comes at a time where opioid-related overdoses have skyrocketed.
Fentanyl is stronger than heroin and cheaper to produce, so drug dealers often mix it with heroin to maximize profits.
The drug was linked to more than 1,400 deadly overdoses in 2017.
