Twenty -five people were picked up on drug and firearm trafficking charges following a two-year investigation into crime networks in Manassas, law enforcement officials announced.

In eight indictments and five criminal complaints unsealed Thursday, the 25 individuals allegedly include a ring of suppliers, mid-level dealers and street-level dealers accused of selling cocaine, heroin and guns.

Undercover cops made 215 controlled buys, and seized 85 guns, 500 grams of crack cocaine and two kilograms of power cocaine, all with a street value of about $1.1 million, authorities said.
