The family of the man accused of throwing petrol bombs at a pro-Israel group in Colorado have been taken into custody.
Immigration officers detained Mohamed Soliman’s relatives, believed to be his wife and five children.
Soliman, an Egyptian national, moved to the US three years ago and lived in Colorado Springs but was there illegally after his visa and work authorisation expired. He reportedly has two teenage children and three younger children.
“We are investigating to what extent his family knew about this heinous attack, if they had knowledge of it, or if they provided support to it,” said homeland security secretary Kristi Noem on X.
Soliman, 45, is being held after Molotov cocktails were thrown at a group doing a walk for Israeli hostages in Boulder on Sunday.
The attacker allegedly yelled “Free Palestine” and had a total of 18 petrol bombs – but police said he “got scared” and only tossed a couple.
Soliman also had a makeshift flamethrower in the form of gas in a backpack sprayer, according to a FBI statement, but told investigators he did not use it.
Twelve people were injured, authorities said. The victims were aged between 52 and 88 and three of them were still being treated in hospital on Tuesday.
Soliman was allegedly dressed as a gardener to get as close as he could to the small group. Authorities said he told them he had no regrets.
He has been charged with a hate crime and 16 counts of attempted murder in federal and state cases.
Court papers said he planned the attack for a year and told authorities that no one, including his family, was aware of the plot.
An FBI statement said Soliman left an iPhone hidden in a drawer at his home with messages for his family but that his wife handed it to police.
The family are said to be cooperating with investigators.
Soliman admitted taking gun training to try to get a permit but was denied as he wasn’t a US citizen, according to police and the FBI.
Barred from buying a firearm, he allegedly used YouTube to learn how to make petrol bombs.

Israeli Prime Minister Benjamin Netanyahu said the Boulder attack was “aimed against peaceful people who wished to express their solidarity with the hostages held by Hamas, simply because they were Jews”.
The incident follows the arrest of a Chicago-born man in the fatal shooting of two Israeli embassy employees in Washington DC last month.
Tensions are simmering in the US over Israel’s war in Gaza.
There has been an increase in antisemitic hate crime, as well as moves by some supporters of Israel to brand pro-Palestinian protests as antisemitic.
