Over 40 members and associates of a violent Boston gang allegedly responsible for multiple murders, racketeering, COVID loan fraud and other crimes were arrested on Wednesday during an operation involving federal and local agencies.

The U.S. Attorney’s Office for the District of Massachusetts, led by Joshua S. Levy, announced the crack-down on Wednesday, following a two-year investigation into gang violence in Boston.

In a press release, Levy’s office said the Heath Street Gang operates out of the Mildred C. Hailey Apartments, which is a public housing development in Jamaica Plain.

The gang was formed in the 1980s, the release read, and is alleged to have over 150 members and to have been involved in violent acts to protect and preserve the gang’s power, territory and reputation.

Some of the drug activity and deals are facilitated through social media platforms, the attorney’s office alleges, and includes the distribution of fentanyl, fentanyl pills, cocaine, cocaine base and marijuana.

Since about 2019, the group has openly stolen merchandise from stores in Massachusetts and New Hampshire and engaged in unemployment fraud using the CARES Act Loan, according to charging documents.

If convicted, suspects charged with racketeering conspiracy, conspiracy to distribute controlled substances, possession with intent to distribute controlled substances, conspiracy to interfere with commerce by robbery, and robbery could be sentenced to up to 20 years in prison and up to a $250,000 fine for each count.

Suspects convicted of being a felon in possession of a firearm and ammunition could get up to 10 years or 15 years for offenses committed after June 25, 2022, and at least five years, and up to life in prison for possession of a firearm in furtherance of a violent or drug trafficking crime.

Joining Levy during the announcement was Boston Police Commissioner Michael Cox; James M. Ferguson of the Bureau of Alcohol, Tobacco, Firearms & Explosives; and Michael J. Krol of Homeland Security Investigations.
