Sheikhdoon Abdullahi Mohamud was arrested Tuesday in a public park in Richfield after paying $600 for a Norinco AK-47 and about 200 rounds of ammunition, according to a federal criminal complaint.
The undercover FBI employee was posing as a member of ISIS, according to news agency AP.
It was not immediately known whether he had an attorney who could comment on his behalf, and AP said it could not immediately identify family members for comment. Rosen said Mohamud is an American-born US citizen of Somali descent. He also urged parents to take seriously any indication that their children may be becoming radicalised.
He appeared in federal court in St Paul on Wednesday wearing a yellow jail uniform.

Agents “were able to detect a threat, and disrupt it, before the defendant carried out his intention to kill, in his words, maybe 30 to 60 people. As per CNN, court records also described Mohamud as appearing to admire other terrorist-related mass-casualty attacks, including the Bondi Beach shooting in Australia and the New Orleans attack in January 2025.
“This was a radicalized young man who needed to be watched,” Rosen said, praising the investigation.
