A Nassau County detective is accused of trying to sexually exploit a child.

Robert Sacco, 38, of Huntington, tried to convince an undercover agent, who he believed was the father of a 10-year-old, to perform sex acts with the child so he could watch, prosecutors say.

The agent started talking to Sacco in October of last year.

The detective was arrested in Brooklyn on Saturday.

Nassau County Executive Bruce Blakeman tells News 12, "The allegations against Detective Sacco are shocking and disgusting. This in no way represents the professionalism and integrity of our outstanding Police Department.”

Sacco had been suspended without pay.
