The officer, Jose Tejada, 45, is also accused of allowing the robbery crew to use his Manhattan apartment for their enterprise.
In court documents filed Wednesday, federal prosecutors said the crew posed as police officers and used fake warrants to arrest drug traffickers.
The crew then robbed those it arrested of their money and their stashes of marijuana, heroin, ecstasy and cocaine, authorities said.
In all, the group — comprised of Tejada and at least 21 others — is responsible for more than 100 armed robberies since 2001 throughout New York city.
Tejada was arrested Wednesday and faces multiple counts of robbery, drug dealing and weapons charges.
An arraignment in the case is scheduled for Thursday afternoon.
It was not immediately known if he had retained a lawyer.
