BOSTON (TNND) — U.S. Immigration and Customs and Enforcement and law enforcement officers arrested 370 individuals dubbed "illegal aliens" in Massachusetts during a six-day targeted operation aimed at taking down transnational organized crime and violent gangs, including MS-13, Tren de Aragua, and the 18th Street Gang.

ICE officials said the operation, which took place from March 18 to March 23, focused on offenders with criminal backgrounds and resulted in the seizure of illegal drugs, firearms and the arrest of fugitives facing serious charges like murder and money laundering.

A large portion of those arrested - 205 individuals - had prior criminal convictions or were facing charges for serious offenses, including violent crimes, drug trafficking and organized criminal activities. Six of those detained were allegedly foreign fugitives wanted for murder, drug trafficking, money laundering, and involvement in organized crime.

The operation also resulted in a haul of illicit drugs and firearms. Officials stated that approximately 44 kilograms of methamphetamines, 5 kilograms of fentanyl, and 1.2 kilograms of cocaine. In addition to these drugs, officers confiscated three firearms along with ammunition, all of which had been in the possession of the arrested suspects.

Officials said that many of the arrests were made after local jurisdictions refused to comply with ICE detainer requests. These jurisdictions had previously released several offenders from custody despite ICE's request to hold them for deportation proceedings, stated the news release from ICE.

Patricia H. Hyde, acting Field Office Director of ICE Enforcement and Removal Operations Boston, highlighted the success of the operation, emphasizing its positive impact on public safety.

"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,” Hyde said in a statement. “Throughout this enhanced enforcement operation, we targeted the most dangerous alien offenders in some of the most crime-infested neighborhoods in and around Boston. Our efforts resulted in 370 arrests throughout the commonwealth. ICE and our federal law enforcement partners are committed to protecting the homeland through the eradication of transnational criminal organizations, dismantling dangerous criminal gangs preying on the American public, locating and arresting criminal alien offenders, and making our communities a safer place to live."
