Police have arrested nine people in connection with an international drug ring.
The arrests were split between the city and a town in upstate Duchess County.
Investigators seized more than 2.5 kilos of cocaine.
Court documents show that the ring was headed by a Washington Heights couple.
Police say they oversaw the operation, which conducted more than 100 transactions a day, some of them in the stairwell of their building, which was located near the George Washington Bridge.
"It was really like a 24-hour cocaine to-go shop. They had a designated pickup location, storage for inventory and round-the-clock delivery personnel," said New York State Attorney General Eric Schneiderman. "And they were getting more than 100 calls a day. This was a high-volume, quick-delivery cocaine operation."
Police say they also maintained a storage, weighing and packing facility in other apartments nearby.
Much of the cocaine was distributed upstate, according to police.
Officials say the proceeds would then be sent to the Dominican Republic.
