MINNEAPOLIS — Federal authorities arrested an 18-year-old Minnesota man after an undercover operation disrupted what prosecutors allege was a plan to carry out a mass shooting at the Mall of America during an October 24 cultural event.
Sheikhdoon Abdullahi Mohamud was charged by criminal complaint with knowingly receiving a firearm and ammunition in order to commit a federal crime of terrorism. The Justice Department said the FBI arrested him October 6 and that he appeared before U.S. Magistrate Judge Elizabeth Cowan Wright on October 7.
The accusation is not a conviction. Mohamud is presumed innocent unless the government proves the charge beyond a reasonable doubt.
Published October 7, 2026, 9:05 p.m. ET. This report is based on the filed federal complaint, the Justice Department's public release and Reuters reporting.
What the complaint alleges
An FBI affidavit says agents had investigated Mohamud since December 2024 and that he exchanged hundreds of messages with a confidential source over approximately 21 months. Prosecutors allege the messages concerned traveling abroad to join a designated foreign terrorist organization or committing a mass-casualty attack in Minnesota.
According to the complaint and Reuters, Mohamud allegedly identified the Mall of America as a target, discussed killing 30 to 60 people and selected October 24 because a Hmong arts event was scheduled there. The government further alleges that he expressed antisemitic and anti-non-Muslim motives and support for ISIS.
Reuters reports that an undercover FBI employee sold Mohamud an AK-47-style rifle, four 30-round magazines and approximately 200 rounds of ammunition for $600 on October 6. Agents arrested him shortly afterward. These facts are prosecution allegations drawn from the complaint and have not been tested at trial.
What is confirmed
- A federal complaint was filed in the District of Minnesota in case 0:26-mj-00760-ECW.
- Mohamud was arrested October 6 and made an initial appearance October 7, according to DOJ.
- The complaint charges one count involving receipt of a firearm and ammunition to commit a federal crime of terrorism.
- No attack occurred and no casualties were reported.
Why it matters
The alleged target is a heavily visited public venue with more than 500 stores, a theme park and an aquarium. Prosecutors say the planned date coincided with a Hmong cultural celebration, making the case relevant not only to counterterrorism but also to the protection of religious, ethnic and cultural communities from targeted violence.
The case also raises recurring questions about long-running informant operations: when agents first identify a credible threat, how they assess capacity and intent, what safeguards govern controlled weapons transactions and how prosecutors distinguish protected speech from criminal preparation.
DINA analysis: safety and due process must travel together
DINA analysis: Disrupting a credible mass-casualty threat before people are harmed is a core public-safety function. Accountability still requires the government to prove each element of the charged offense with admissible evidence and to disclose the role its sources and undercover personnel played.
Public reporting should avoid treating allegations as adjudicated fact or using one defendant to stigmatize a broader religious, immigrant or ethnic community. The alleged threat should be examined through evidence, individual responsibility and due process.
Urgent follow-up
- Track the detention proceedings, appointment or appearance of defense counsel and any indictment replacing the complaint.
- Request the public docket, arrest records and future hearing transcripts.
- Seek the FBI's policies governing confidential-source contacts, threat assessment and controlled firearms transactions, with lawful redactions.
- Ask Mall of America officials what public-safety measures will apply to the October 24 event without publishing operational vulnerabilities.
- Monitor whether prosecutors add, reduce or dismiss charges as evidence is tested.
