TRENTON, N.J. ? Six law enforcement officers were indicted Tuesday on charges alleging they tipped off a suspected drug ring about police raids in exchange for drugs.

What began as a “social relationship” between the northern New Jersey officers and their young contemporaries soon spiraled out of control, authorities said.

The main drugs involved were the powerful painkiller OxyContin and the sleeping pill Ambien.

The officers were arrested within the past 18 months, but the case was made public Tuesday with the indictments.

Each officer was suspended and faces arraignment in four to six weeks on charges including conspiracy to commit official misconduct, conspiracy to possess narcotics, official misconduct, witness tampering and hindering apprehension.

The indictment also names seven others who were targeted in the drug probe, which included dealing in cocaine, OxyContin and anabolic steroids.
