Authorities say they have seized over 40 pounds of fentanyl six blocks away from El Divino Nino Day Care in the Bronx, where a 1-year-old child was fatally exposed to fentanyl.

Police found the fentanyl as part of an investigation into fentanyl trafficking in the city. Officers arrested Juan Gabriel Herrera Vargas in connection to the discovery. He is being charged with operating as a major trafficker, criminal possession of a controlled substance and more.

The Special Narcotics Prosecutor's Office says police conducted surveillance on Heath Avenue Tuesday in the Bronx. Vargas was seen carrying a small black bag to the Kingsbridge Road subway station, they say. Officers tracked Vargas as he traveled south and later made a northbound return trip on the subway. He was then seen exiting the Kingsbridge Road station and walked toward an apartment building at 2800 Heath Ave. pulling a rolling suitcase, according to authorities.

Officers approached Vargas, and he handed the agents his wallet and identification before allegedly attempting to flee and leaving behind the suitcase. The NYPD discovered 13 kilogram bricks of suspected fentanyl in the suitcase.

A few hours later, Vargas was seen exiting an apartment in the same building with a blue suitcase. Police say they arrested Vargas and seized "50,000 glassines wrapped together into 25 larger packages from inside the suitcase."

Authorities then searched the apartment and found 1 kilogram of suspected fentanyl, 6 pounds of loose powder, 10,000 filled glassines and materials used for packaging glassines. More fentanyl and packaging materials were discovered as well as a security camera police believe could monitor the apartment. The apartment windows were taped up with large plastic bags to prevent visibility into the apartment.
