Between August 2025 and March 2026, approximately 64,000 people were arrested by ICE during street sweeps as "collateral" arrests—detained based on appearance or proximity to someone with a warrant rather than having individualized warrants themselves. These collateral arrests represented roughly a quarter of ICE's 253,000 total arrests during this period. About 70% of collateral arrests involved only immigration-related violations, compared to 41% of warrant-based arrests, and less than 2% involved violent crime convictions. Multiple lawsuits have challenged the legality of these arrests, and arrest numbers declined following public outcry.
