The family of the man accused of attacking a group of people Sunday with Molotov cocktails and a makeshift flamethrower has been taken into ICE custody and are being processed, a DHS official confirmed to CNN Tuesday.

A construction law attorney in Colorado has been receiving death threats due to being mistaken as the immigration attorney representing the family of Mohamed Soliman, the suspect of the Boulder terror attack.

Homeland Security Secretary Kristi Noem said the agency would be investigating whether Mohamed Sabry Soliman’s family had information about his alleged plot.
