A Guatemalan national with 28 separate adult arraignments on his record, including charges of strangulation, witness intimidation and assault with weapons ranging from a knife to a machete, has been arrested by federal immigration agents in Brockton. U.S. Immigration and Customs Enforcement announced the arrest of Santos Porfillo Peres Rodrigues, a case the agency is holding up as an example of the kind of repeat offender its Boston field office says it is targeting for removal.
ICE Boston took Rodrigues into custody in Brockton, according to Fall River Reporter, which first reported the arrest. The outlet's account lists a lengthy string of charges tied to Rodrigues's arraignments, among them assault and battery on a family or household member, assault and battery on a person over 60 or disabled, assault and battery with a dangerous weapon involving a stick, tree branch or blunt object, assault with a dangerous weapon involving a knife and assault with a dangerous weapon involving a machete. Additional charges cited include trespassing and general assault and battery counts. It remains unclear whether Rodrigues has previously been deported, as ICE did not disclose that information in connection with this arrest.
Why Local Police Couldn't Hold Him
The arrest illustrates a recurring friction point in Massachusetts immigration enforcement: an arraignment is a formal criminal charge presented in court, not a conviction, and state law bars local police from detaining someone solely on a federal civil request once local custody ends. That restriction traces back to the Massachusetts Supreme Judicial Court's 2017 ruling in Lunn v. Commonwealth, which found, per the Harvard Law Review, that state law gives police no authority to hold people on civil ICE detainers alone.
Those civil detainers, formally known as ICE Form I-247A, ask local agencies to hold someone for up to 48 hours before release, but they are administrative requests signed by immigration officers rather than judicial warrants signed by a judge, according to the Congressional Research Service. Because repeat defendants who complete their court proceedings at venues like Brockton District Court cannot be held by court officers purely at ICE's request, the agency's Boston field office has had to deploy its own deportation officers for targeted at-large arrests in communities like Brockton rather than relying on local custody holds, per the same reporting on ICE's enforcement posture.
State's New PROTECT Act Adds Another Layer
The legal landscape shifted further in July 2026, when Massachusetts lawmakers passed the PROTECT Act, which bars new 287(g) agreements for civil immigration enforcement, restricts police collaboration with ICE and prohibits civil ICE arrests inside state courthouses, according to the ACLU of Massachusetts. The law reinforces the same dynamic established by the Lunn decision: ICE must rely on independent field operations rather than local law enforcement cooperation to make arrests like the one in Brockton.
Federal Prosecutors Expanding Role in Plymouth County
In August 2026, the U.S. Department of Justice awarded the Plymouth County District Attorney's Office more than $700,000 to cross-designate a state prosecutor as a Special Assistant U.S. Attorney, a role focused on multi-jurisdictional cases including criminal immigration matters.
Rodrigues is a Guatemalan national.
The Brockton arrest follows a string of recent ICE enforcement actions across Massachusetts that Hoodline has covered, including an I-81 trooper death case tied to another Brockton man, as well as arrests in Lowell, Marlborough, Springfield and Billerica involving noncitizens facing serious local charges.
