Federal immigration and law enforcement officials conducted a six-day “enhanced targeted enforcement operation focusing on trans-national organized crime, gangs, and egregious illegal alien offenders” in Massachusetts over the last week, announcing on Monday the apprehension of 370 individuals.

Enforcement and Removal Operations (ERO) Boston, a law enforcement directorate within US Immigration and Customs Enforcement, said 205 of the people arrested during the March 18-23 focus on Massachusetts “had significant criminal convictions or charges,” including six foreign fugitives currently facing charges or convictions for murder, drug trafficking, organized crime, and money laundering.

Federal officials said they also seized 44 kilograms of methamphetamine, five kilograms of fentanyl, just more than one kilogram of cocaine, three firearms, and ammunition from “illegal alien offenders.”

“The Commonwealth is a safer place for our residents to live and work because ICE and our federal law enforcement partners arrested hundreds of alien offenders and removed them from the streets of Massachusetts,” ERO Boston Field Office Acting Director Patricia Hyde said. “Throughout this enhanced enforcement operation, we targeted the most dangerous alien offenders in some of the most crime-infested neighborhoods in and around Boston.”

The agency’s press release says arrests were made in Boston, Marlborough, Worcester, Salem, Milford, Lowell, Medford, Wakefield, New Bedford, Pittsfield, and West Yarmouth.

Trump border czar Tom Homan, who promised to bring “hell” to Boston as he called out Mayor Wu earlier this year, said on Monday that he visited Boston at the start of the sweep last Tuesday. The FBI on Monday shared photos of the command center it established to support the federal immigration enforcement effort, including pictures from Homan’s visit.
