Owners of a pair of mom and pop drug stores were arrested for allegedly running one of the largest prescription pill mills in the city's history. NY1's Dean Meminger filed the following report.

Released on $100,000 bond, Robert Cybulski did not want to speak as he left federal court Thursday. He's charged with participating in a massive Oxycodone ring that pumped painkillers out of mom and pop pharmacies in Brooklyn and Queens.

"The defendants illegally distributed more than 500,000 tablets of oxycodone over a five-year period, pills with a street value of $10- and $15 million," said Preet Bharara, U.S. attorney for the southern district of New York.

Prosecutors and the Drug Enforcement Administration say pharmacist Lilian Wieckowski and her husband, Marcin Jakacki, illegally sold 760,000 Oxycodone pills, more than 400,000 without any doctor's prescription.

Their Chopin Chemists pharmacies on Manhattan Avenue in Brooklyn and Fresh Pond Road in Queens were allegedly the center of their operation.      

"Using her position to sell hundreds of thousands of Oxy tablets to dealers for further re-sale on the street, fueling opioid abuse and addiction," said James Hunt, the special agent in charge of the DEA in New York. "From DEA's perspective, Wieckowski is nothing more than a white-collar drug dealer."

The DEA does audits of pharmacies to make sure they're distributing drugs correctly. The Chopin Chemists immediately set off alarms.

"For three straight years, from 2010 to 2012, its Brooklyn location was the number one purchaser of Oxycodone in the entire area covered by that zip code," Bharara said.

"Well, it is certainly out of the ordinary when a small pharmacy would sell more than a CVS or Rite Aid," Hunt said.

Prosecutors say once the owners found out their Brooklyn pharmacy was being investigated, they actually shut it down and moved the pill operation to their Queens drug store.

It's alleged that Cybulski was the pharmacy's biggest buyer, often purchasing hundreds of pills at a time and distributing them on the street.

The owners were given $1 million bond each and have to use their $2 million mansion in Greenwich, Connecticut as security.

While detailing the arrests, the US attorney and DEA released a public service announcement discouraging people from abusing prescription drugs.
