Agents from multiple federal agencies carried out immigration enforcement operations in Austin and San Antonio on Sunday, federal officials said.

U.S. Immigration and Customs Enforcement, along with the Drug Enforcement Agency, the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives collaborated on “enhanced targeted operations” in both cities, an ICE spokesperson said. A similar operation took place Sunday morning in the Rio Grande Valley, a local station reported.

The spokesperson said the operations were to “enforce U.S. immigration law and preserve public safety and national security by keeping potentially dangerous criminal aliens out of our communities.” The official did not say what kind of offenses the targeted individuals were suspected of committing or whether anyone was detained.

KXAN first reported ICE was conducting an operation in the Austin area on Sunday afternoon through a spokesperson for the DEA’s Houston division. DEA spokesperson Sally Sparks said the agency’s Houston office “mobilized every agent in our division,” whose jurisdiction spans from Brownsville to Corpus Christi, Del Rio and Waco.

“We got information that we had to mobilize, so we mobilized,” Sparks told The Texas Tribune. “The majority of our agents assisted.”

A Houston DEA post on X on Sunday showed photos of law enforcement officers in a residential area escorting a man in handcuffs.

Neither ICE nor the DEA answered questions about the scale of the operations. Spokespeople for the Travis and Bexar counties’ sheriff’s offices said they had not been notified of the operations. A spokesperson for U.S. Rep. Lloyd Doggett, D-Austin, said Doggett did not receive advance notice that ICE would conduct an operation in Austin.

Sunday’s operations came less than one week after President Donald Trump began his second term as president and promised mass deportations across the country. Trump issued more than a dozen immigration-related executive orders last week, including halting the use of an app that lets migrants make appointments to request asylum and authorizing immigration officers to raid sensitive locations such as churches, schools and hospitals.

The Trump administration has also directed federal officials to investigate and potentially prosecute local officials who interfere with deportation efforts. Some local Texas officials said they are ready to assist Trump, though they have offered scant details on how they would cooperate. A group of Texas lawmakers asked state education officials last week for clear guidance on how school districts should prepare for federal immigration enforcement.

Federal officials also conducted raids in Chicago on Sunday, and ICE officials have been directed to increase the number of people they arrest from a few hundred per day to at least 1,200 to 1,500, The Washington Post reported Sunday. ICE made 956 arrests Sunday and sent 554 requests to take custody of individuals currently being held in jails, prisons or other confinement facilities, the agency said in a Sunday evening post on X.

Trump’s actions over the past week have left some migrants stranded on the U.S.-Mexico border, and the threat of deportation has left others in fear. Texas is home to approximately 1.6 million undocumented people, according to a Pew Research Center Report.
