The Lawrence, Massachusetts, Police Department arrested 22 people on June 19 in connection with a major anti-drug operation.
Police seized bags of heroin and over $4,000 in cash from both heroin dealers and their customers.
Those arrested range from age 17 to 59 years old. Police say the trade was conducted in Lawrence due to its proximity to the highway and New Hampshire border.
"Today we sent a message to drug dealers and those who think they can come to our city to purchase narcotics with impunity that we will not tolerate this dangerous and illegal activity." said Police Chief James Fitzpatrick. "We are out there, and we are watching. We will find you. We will arrest you. Lawrence is not a city that will tolerate the proliferation of poisons in and around our community."
The investigation was conducted in conjunction with several law enforcement agencies in Massachusetts and New Hampshire.
