The family of the suspect in the Boulder, Colo., anti-Semitic terror attack has been arrested by federal immigration authorities, Secretary of Homeland Security Kristi Noem announced Tuesday.

"Today, the Department of Homeland Security and ICE are taking the family of suspected Boulder, Colo., terrorist and illegal alien Mohamed Soliman into ICE custody," Noem said in a video posted on X. "Now, Mohamed's despicable actions will be prosecuted to the fullest extent of the law, but we're also investigating to what extent his family knew about this horrific attack—if they had any knowledge of it or if they provided support to it."

Fox News's Bill Melugin reported the news earlier that afternoon, writing that senior sources within the department said authorities are processing Soliman's family for "expedited removal."

The news comes as the Trump administration has ramped up deportations of illegal immigrants. Under border czar Tom Homan, ICE has arrested more than 158,000 illegal aliens, around 75 percent of whom have criminal convictions or pending charges, according to the DHS.

Soliman, a 45-year-old illegal immigrant from Egypt, on Sunday threw Molotov cocktails and used a makeshift flamethrower on peaceful Boulder, Colo., demonstrators—injuring 12 victims, including a Holocaust survivor.

The Justice Department on Monday charged Soliman with a federal hate crime. Soliman is also facing state charges of 384 years for 16 counts of attempted murder, 48 years for 2 counts of using an incendiary device, and 192 years for 16 counts of attempted use of an incendiary device, according to Boulder district attorney Michael Dougherty.

Soliman, who entered the United States in August 2022 on a tourist visa and has remained illegally in the country after his visa expired in February 2023, admitted in a police interview Monday that he "wanted to kill all Zionist people." Soliman told investigators that he had planned the terror attack for a year and "would do it again."
