Texas immigration sweep nets 4,170 arrests in 10 days

The Department of Homeland Security arrested 4,170 people in Texas over a ten-day period, according to data released on Thursday. The figures cover a specific enforcement window that ended on October 29, 2026.

Markwayne Mullin, the Secretary of Homeland Security, presented the results of the operation in Dallas. He labeled the effort the Lone Star Mission and described it as an incredible success. Mullin credited President Donald Trump’s leadership for the outcome and thanked Texas state law enforcement for their cooperation.

The operation ran from October 19 to October 29. It involved the five regional offices of Immigration and Customs Enforcement located in Dallas, Houston, San Antonio, El Paso, and Harlingen. These jurisdictions cover the border state of Texas. The government stated that all detainees were in irregular immigration status.

DHS officials noted that the group included individuals linked to homicide, sexual assault, driving under the influence, and migrant smuggling. However, the department did not specify how many of the 4,170 arrestees had criminal records or pending charges. It also did not clarify how many were detained solely for immigration violations.

The announcement comes four days before the legislative elections scheduled for November 3. It fits into a wider campaign of arrests and deportations that began when Trump returned to the White House in January 2025. The administration has maintained that its primary focus is on migrants with criminal histories.

A study published by the University of Colorado in July offered a different perspective on that priority. The research found that only 34 percent of people arrested by ICE during the first fourteen months of the Trump administration had a criminal conviction. The new Texas figures add to the record of enforcement actions taken in the border region this year.
