Four construction workers were detained by U.S. Immigration and Customs Enforcement on Thursday, August 6, 2026, following a traffic stop conducted by Texas Department of Public Safety troopers outside Austin City Hall. DPS troopers, who are federally certified Designated Immigration Officers under the 287(g) program, pulled over a vehicle at Guadalupe Street and César Chávez Street after observing it driving the wrong way on a one-way street just before 9:30 a.m. The driver did not have a valid driver's license. After determining that all four occupants were not lawfully present in the United States, troopers contacted ICE agents, who arrived within three to four minutes and took the individuals into custody, confiscating their phones. The detention occurred while the Austin City Council was holding a budget meeting, and community members expressed outrage during public comment. By Thursday evening, family members did not know where the detainees had been taken. City Council members, including Mike Siegel, condemned the operation, with Siegel characterizing it as "state-sponsored kidnapping" and criticizing the collaboration between DPS and ICE.
