Local, state and federal law enforcement officials say they have busted a "high level heroin trafficking organization" in western Massachusetts.
The Hampden district attorney said Tuesday that police seized 6 kilograms of heroin and arrested 10 people during the execution of several simultaneous raids on Monday in Springfield.
The 6 kilograms of heroin would conservatively yield more than 450,000 bags of heroin on the street, with a street value of more than $1.3 million.
In addition, police seized 4,500 ready-for-sale bags of heroin, six guns and four motor vehicles.
Those arrested were all from either Springfield or New York City. All are being held on bail ranging from $1,000 to $250,000.
Hampden District Attorney Anthony Gulluni says city streets "are appreciably safer today with these individuals in custody."
