Reputed Mafia boss John Gotti paid off a police officer for a tip that authorities had bugged the office of a Gotti cohort, police say.

Detective William J. Peist, 43, was stripped of his shield and guns and put on desk duty after refusing to cooperate with the FBI, police said Monday.Peist faces departmental charges for failing to cooperate. No criminal charges were immediately filed.

Meanwhile, the judge in Gotti's racketeering case Monday postponed until Friday a bail hearing while he considers a defense request to close the hearing to the public.
