U.S. Immigration and Customs Enforcement (ICE) arrested 4,170 illegal immigrants across Texas during a 10-day enforcement operation targeting individuals living in the country illegally, including people with criminal convictions and outstanding warrants.

The operation, called Lone Star Mission, ran from October 19 through October 29 and involved coordinated efforts by ICE Enforcement and Removal Operations (ERO) offices in Dallas, Houston, San Antonio, El Paso and Harlingen.

Department of Homeland Security Secretary Markwayne Mullin announced the results Thursday, October 29, during a press conference in Dallas alongside regional ICE leadership. He credited cooperation between federal authorities and Texas law enforcement agencies for allowing officers to carry out the statewide operation.

“Lone Star Mission has been an incredible success, with the brave patriots of ICE arresting more than 4,100 illegal aliens across the state of Texas in ten days,” Mullin said.

“Thanks to Texas law enforcement and our federal partners, over the course of this operation, we arrested murderers, sexual assailants, drunk drivers, and alien smugglers. This operation shows exactly how important our state and local partnerships are for protecting American communities.”

According to Mullin, more than 60% of those arrested had criminal backgrounds. The remaining 40% did not have criminal records, although some were taken into custody during operations targeting other individuals. Mullin described these as collateral arrests, explaining that individuals could be encountered at a residence or inside a vehicle where officers were executing an arrest.

Among those arrested were individuals with convictions or cases involving burglary, sexual assault, driving under the influence, illegal reentry, and human smuggling.

Federal officials highlighted several arrests involving individuals with serious criminal histories.

In Liberty, ICE arrested Javier Hernandez Alcon, a Mexican national who had previously been deported from the United States twice. His criminal history includes convictions for burglary of a residence and illegal reentry, as well as an arrest for capital murder.

In Houston, officers arrested Ramon Antonio Martinez, a Honduran national wanted in his home country in connection with a murder investigation. Authorities said he was wanted in connection with the killing of a Honduran man alongside two other suspects.

ICE officers also arrested Gerardo Daniel Rivera-Rivera in Zapata County. The Mexican national had convictions for felony sexual assault and illegal reentry.

In El Paso, officers took Victor Manuel Macias-Castro into custody. DHS identified him as a Mexican national and member of the La Linea Cartel, with convictions involving illegal entry, illegal reentry, and conspiracy to transport or harbor illegal immigrants.

Another arrest occurred in Dallas, where officers apprehended Orlando Aguilar, a Mexican national with convictions for felony intoxication assault involving a vehicle that caused serious bodily injury and driving while intoxicated.

North Texas accounted for 879 of the 4,170 arrests made during the operation, according to ICE figures.

Mullin said the coordinated effort gave federal authorities the resources to locate individuals they had been attempting to apprehend for extended periods. He explained that officers were able to conduct additional investigative work to establish where targets lived and worked before carrying out arrests.

The operation also highlighted the expanding partnership between ICE and Texas law enforcement. More than 400 agreements under the federal 287(g) program had been signed with Texas law enforcement agencies, allowing participating departments to assist federal immigration authorities in carrying out certain immigration enforcement responsibilities.

More than 140 additional agreements were pending as of October 30.

Mullin also pointed to the broader enforcement effort underway under President Donald Trump's administration. He said Texas ICE Enforcement and Removal Operations officers took more than 136,000 individuals with criminal backgrounds into custody between October 2025 and September 30, 2026.

The Homeland Security secretary indicated that targeted immigration enforcement would continue, while acknowledging that the scope of future operations would depend on available personnel and resources.

The announcement comes as the Trump administration continues its nationwide effort to locate and deport illegal immigrants, with federal officials emphasizing the removal of individuals who have committed crimes or pose public safety concerns.

Texas has remained a major center of immigration enforcement, with federal authorities relying heavily on cooperation from state and local agencies to carry out arrests across the state.
