DALLAS — At least two detainees were shot at an US Immigration and Customs Enforcement facility in Dallas on Wednesday morning, according to two law enforcement officials with knowledge of the incident.

A suspect is dead from a self-inflicted gun shot wound, Homeland Security Secretary Kristi Noem said on X.

“Details are still emerging but we can confirm there were multiple injuries and fatalities,” Noem’s post read. The motive in the shooting is unknown, she said.

Acting ICE Director Todd Lyons said on CNN earlier Wednesday three people were shot, all of whom were taken to a hospital. He did not specify who the three people were.

“Preliminary information is a possible sniper,” Lyons said.

ICE employees, civilians, and immigrant detainees are generally among those at the facility.

Wednesday’s shooting marked at least the third instance of an ICE or Customs and Border Protection facility being targeted by gunfire in Texas this year.

On July 4, a group of assailants targeted the Prairieland Detention Center, near Fort Worth, in what authorities described as a coordinated attack that left a local police officer shot in the neck. The officer survived, and more than a dozen people have been charged for their alleged roles in the attack.

Days later, a 27-year-old man with a rifle and tactical gear was killed by police after he opened fire on a Border Patrol facility in McAllen. Two officers and a Border Patrol employee were injured, and dozens of rounds were exchanged between the shooter and law enforcement. — CNN
