A large-scale drug sweep Tuesday morning in Brockton has led to the arrest of 15 city residents and one Rockland man for allegedly dealing fentanyl and cocaine.

Fentanyl, oxycodone and other drugs worth around $350,000 have been seized in a massive drug trafficking operation bust in Bristol County after a year-long investigation led by a state police task force with help from multiple other agencies.

Authorities seized more than three kilos of cocaine, nearly 55 grams of crack, loose fentanyl and fentanyl pills, a stun gun, and more than $9,000 in cash.

Authorities said a drug bust in Fall River led them to a narcotics trafficker in Lawrence.
