BOSTON — Arson. Disposing of a human body. Child cruelty. Assault with a knife. Four separate drug dealing convictions.
These are the criminal records of illegal immigrants that Boston police released back onto the streets after denying ICE immigration detainers — and on Wednesday, the federal agency decided to put every last one of them on blast.
ICE dropped a thread on X naming eight criminal illegal immigrants its Boston field office was forced to track down and arrest after the city's police department refused to hold them for federal agents. The agency also accused Boston PD of lying about the scale of the problem — claiming the department said it denied just 57 detainers when the real number was over 167 in 2025 alone.

TRUTH: Sanctuary city Boston PD denied over 167 ICE immigration detainers in 2025 and released these criminals BACK onto Boston's streets.
Here are just a few of the…
Then came the names.
The lineup
Oliver Gaffey Oswin, a Barbadian national, tops the list with convictions for arson, improper disposal of a human body, drug violations, and driving offenses. His rap sheet also includes arrests for strangulation, suffocation, and domestic violence. Boston police had him — and let him go.

Eight names. Eight mugshots. Eight criminals that Boston police could have handed over to federal agents — and chose not to.
The bigger picture

The thread is the latest salvo in an ongoing war between federal immigration authorities and Boston's sanctuary city policies under Mayor Michelle Wu. ICE has repeatedly accused the city of prioritizing ideology over public safety.
The city council, for its part, recently voted 9-4 to block the public from learning whether denied ICE detainers involved actual criminals. ICE just answered that question for them — with names, nationalities, and rap sheets.
ICE director previously called Boston's approach "politically motivated." Wednesday's thread suggests the agency has moved past words.
One hundred and sixty-seven denied detainers. Eight dangerous criminals named publicly. And a police department that, according to the federal government, understated the numbers by two-thirds.
Boston PD has not responded to the thread.
