After resigning from the NYPD for beating a handcuffed suspect, an ex-cop pursued a second career as a leader of a drug trafficking organization that imported meth from Mexico and date rape drugs from China, prosecutors say.

John Cicero and four others were charged in February with running the drug ring that moved “large quantities” of meth and GBL into the city and Westchester. In a new filing in Manhattan Federal Court opposing Cicero’s request for bail, prosecutors revealed the extent of the ex-cop’s alleged criminal enterprise.

Cicero, 38, was busted on Feb. 19 at the Andaz Wall Street Hotel in a room rented under a fake name, prosecutors said. The feds found meth and GBL in the room. Cicero had a Connecticut ID with his photo and a fake name, along with a bank card with the alias, according to prosecutors.

Further searches, including at the Westchester co-op apartment belonging to Cicero’s parents, found credit card-making machines and notebooks with personal information of 89 people, prosecutors wrote.

In 2017, U.S. Customs & Border Protection seized 6.6 kilos of GBL from China bound for the apartment belonging to Cicero’s parents, according to Assistant U.S. Attorney David Felton wrote. An investigation into a meth supplier in Mexico whose name was saved in Cicero’s phone is ongoing, the prosecutor wrote. The phone also had a photo of multiple kilos of meth on a scale, authorities say.

“The vast, no-doubt-about-it evidence of Cicero’s guilt and his leadership role create every incentive for the ex-NYPD officer to flee and not serve the 10-year mandatory minimum sentence that he faces, especially given his familiarity with credit card making equipment, notebooks full of stolen identities, and use of an alias sufficient to dupe a luxury hotel,” Felton wrote.

Cicero pleaded guilty to misdemeanor assault for beating a handcuffed man on a Bronx sidewalk on Jan. 5, 2010. He received only 400 hours of community service — though prosecutors had asked for a 60-day jail sentence.
