IMMIGRATIONImmigration Street Sweeps Led to More “Collateral” Arrests of Noncriminals
A quarter of immigration arrests since August were labeled by U.S. Immigration and Customs Enforcement as “collateral,” a type of arrest and detention that’s been challenged in court as an end run around civil rights. 70% of collateral arrests are for immigration-related crimes or violations only.
A quarter of immigration arrests since August were labeled by U.S. Immigration and Customs Enforcement as “collateral,” a type of arrest and detention that’s been challenged in court as an end run around civil rights.
Public outrage and lawsuits over the arrests may be tamping down the large-scale sweeps that foster them, but tens of thousands were arrested this way between August and early March.
Immigration arrests are usually based on warrants obtained ahead of time, showing either a removal order from immigration court or evidence of a crime or charge that makes the person subject to deportation.
But collateral arrests can result from street sweeps and raids in which a person is singled out for questioning based on appearance or proximity to someone wanted on a warrant. That person could be taken into custody if agents think they may be subject to deportation and also likely to flee if released.
Labeled for the first time ever, the collateral arrests are reported from August to early March in ICE arrest data obtained by the Deportation Data Project and analyzed by Stateline. In that time there were about 64,000 collateral arrests, a quarter of the 253,000 total arrests by ICE.
About 70% of the collateral arrests were for people with immigration-related crimes or violations alone, compared with 41% for arrests with warrants. Less than 2% of those with collateral arrests were convicted of a violent crime, one-third the rate of other arrests, and only 18% were convicted of any crime, compared with 33% for other arrests.
The collateral arrests contributed to an overall pattern of lower and lower shares of arrests for serious crimes, and more for immigration offenses alone.
Arrests climbed from about 12,000 in January 2025 to more than 40,000 in December, but fell back to 30,000 this February. The share of people with only immigration-related crimes and violations rose to more than half in December and January, the peak months for collateral arrests, and the share of violent criminals fell from 10% to 4% of arrests in that time.
New Policy
ICE announced a new policy in January to issue warrants in real time if agents think an immigrant is deportable and “likely to escape,” though that policy faces a court challenge.
Total arrests and collateral arrests have been falling since December, whether because of the new policy or because of cutbacks in the large-scale street sweeps that tend to produce them.
