More information on the busted heroin operation that was serving New York, New Jersey, Washington DC, and Philadelphia.

New Jersey Attorney General Jeffrey Chiesa said authorities arrested 15 people and seized three kilograms of bulk heroin worth more than $300,000 wholesale.

Authorities also netted nearly 500 bricks of the drug that were ready for resale and could fetch upward of $1 million.

The network operated out of a series of heroin mills and stash houses in Paterson, Chiesa said.

Police called this a sophisticated operation.
