EAST ORANGE, N.J. (AP) — Authorities say they have arrested 12 people in a multimillion-dollar drug-trafficking operation in New Jersey.

The East Orange Police Department announced Saturday that state and federal authorities had completed an investigation into a network of heroin and marijuana sales in Essex County. Investigators estimate that the group earned several million dollars a year by trafficking drugs and counterfeit money.

The investigation resulted in about 120 criminal charges, which included possession and distribution of drugs and aggravated assault. Authorities seized more than $356,000 worth of drugs, a firearm, $4,000 in counterfeit money and six vehicles.

Additional arrests are expected.
