The allegation against Vargas is one of a batch of corruption cases in recent years against NYPD officers accused of abusing the FBI-operated National Crime Information Center database to cyber snoop on co-workers, tip off drug dealers, stage robberies and - most notoriously - scheme to abduct and eat women.

The cases aren't confined to New York. In the last six years, authorities have accused a Memphis police officer of using the NCIC database to leak information to a confidential informant about a watch dealer who the informant believed had stolen a Rolex; a reserve patrolman in Clarkston, Ga., of running names and license plates for marijuana dealers; a Montgomery County, Md., officer of running checks on cars belonging to a woman who later reported that the vehicles had been vandalized; and a Hartford, Conn., police sergeant of supplying database records to a woman who used them to harass her ex-boyfriend's new girlfriend.
