After a two-month investigation, the DEA, State Police and Brockton Police teamed up and arrested four men and seized three guns, along with bags of cocaine and fentanyl.
Police raided three apartments on Warren Avenue and investigated a Jeep Cherokee, all of which were under surveillance.
Police arrested Steve Gomes Depina, 28, of Brockton after he reportedly sold heroin and fentanyl to an undercover detective on six separate occasions. He was arrested in his Jeep when he pulled into his apartment. Police recovered eight grams of fentanyl.

Police went into the basement of the apartment building and reportedly found a Glock 23 40-caliber handgun with a high capacity magazine, a small amount of fentanyl in a cigarette pack, a digital scale and plastic baggies.
Officers charged Depina with narcotics sales, unlawful possession of a large capacity firearm, unlawful possession of ammunition, possession of a firearm without an FID card, possession of a Class B substance with intent to distribute and driving without a license.
While one team went after Depina, another team executed another warrant on Warren Avenue. Four men were in the second floor apartment, two of whom were not connected with the investigation. Police arrested Miguel Fidalgo, 32, of Brockton and Joshua Pires, 25, of Dorchester.
Officers said that they found baggies of cocaine on Fidalgo. When they searched the bedroom, officers said they found a loaded Smith & Wesson 1911 45-caliber handgun, which was later determined to have been stolen from Billerica.
Fidalgo was charged with possession of a firearm without an FID card, unlawful possession of ammunition, receiving stolen property, and possession of a Class B substance with intent to distribute.
Pires gave police permission to search his car, which was parked in the rear parking lot. Officers said they found baggies of cocaine in the dashboard console. He was charged with possession of a Class B substance with intent to distribute.
Police executed a third search warrant on Warren Avenue, where they found a 40-caliber Highpoint handgun in a suitcase, wrapped in a red bandana. They said they found ammunition in a nearby closet. Officers charged Joao Pires-Depina, 33, with possession of a firearm without an FID card and unlawful possession of ammunition.
