PATERSON A West Milford resident who is a member of the Ringwood police force became the third lawman to be arrested and accused of leaking confidential information to a ring of steroid dealers. The charges against Officer Paul Kleiber following a 14-month investigation by the Passaic County prosecutor’s office. The leaks happened when Kleiber was assigned to the county’s narcotics task force last year as an undercover officer attempting to buy steroids and other drugs at World Gym in Wayne, said Jay W. McCann, chief assistant Passaic County prosecutor. Kleiber tipped the steroid ring to the investigation in July 2004 and compromised the investigation, McCann said. ``People had an opportunity to dispose of drugs in their possession before the warrants were issued at several locations,’’ he said. Authorities charged 15 people with being part of the ring in August 2004, he said. Kleiber is charged with official misconduct, conspiracy and hindering prosecution, and could face up to 10 years in prison if convicted on all charges. Kleiber, a three-year member of the Ringwood department, was been suspended and a decision is pending on whether to withhold pay, Ringwood Chief Bernard Lombardo said. Arrested last year in the case were Pompton Lakes Patrolman Dennis DePrima and Detective Cpl. Gerry Ward of the Passaic County Sheriff’s Department. More arrests are expected, the prosecutor’s office said.
