ICE’s ‘Collateral’ Arrests Sweep Up Thousands of Noncriminal Immigrants in PA and Beyond

Since August 2025, U.S. Immigration and Customs Enforcement has increasingly relied on a controversial practice called “collateral” arrests — rounding up immigrants without preexisting warrants or removal orders during street sweeps and raids. According to data obtained by the Deportation Data Project and analyzed by Stateline, about 64,000 of the 253,000 total ICE arrests in that period were collateral, a staggering 25 percent.

Unlike traditional arrests based on warrants tied to removal orders or criminal charges, collateral arrests often target people simply because they are near someone wanted by ICE or because agents suspect they might flee. This approach raises serious civil rights concerns, as it effectively allows warrantless detentions based on appearance or circumstantial factors.

The data reveals that collateral arrests disproportionately affect people with no violent criminal convictions — less than 2 percent of those arrested collateral faced violent crime charges, compared to 6 percent in warrant-based arrests. Instead, 70 percent of collateral arrests were for immigration-related violations alone, reflecting a shift toward mass deportation tactics rather than focused enforcement.

The surge in collateral arrests contributed to a sharp decline in the share of ICE arrests involving serious crimes. Arrests peaked at over 40,000 in December 2025, with more than half involving only immigration offenses and violent crime arrests dropping to just 4 percent. Since then, total arrests and collateral arrests have fallen somewhat, possibly due to new ICE policies requiring real-time warrants — a move already challenged in court.

Public backlash against these aggressive sweeps has been fierce. In cities like Minneapolis and Chicago, widespread outrage and lawsuits have pressured ICE to pause large-scale operations that snare noncriminal immigrants. Colleen Putzel-Kavanaugh of the Migration Policy Institute notes that the Trump administration’s emphasis on mass deportations paved the way for these resource-light, high-volume arrests, which would be impossible under more targeted enforcement.

Legal challenges are mounting. In Washington, D.C., a class-action lawsuit alleges ICE agents indiscriminately arrested Latino residents without warrants or probable cause, leading to a court injunction halting such practices. Plaintiffs like José Escobar Molina, a Salvadoran with protected status, recount being forcibly detained without questions.

Similar suits have emerged in Idaho, North Carolina, and Illinois, where citizens and visa holders report being wrongfully arrested during ICE’s collateral sweeps. These cases highlight the racial profiling and civil liberties violations baked into the collateral arrest strategy.

Despite ICE’s claims that new policies address these concerns, judges have found ongoing violations, including issuing warrants after detentions rather than before. The continuation of collateral arrests threatens to undermine democratic principles and community trust, fueling fear and instability among immigrant populations.

As ICE’s tactics come under scrutiny, it is clear that warrantless, collateral arrests represent a dangerous expansion of enforcement powers — one that must be stopped to protect civil rights and uphold the rule of law. We will keep tracking these abuses and the resistance fighting back.
