The FBI says it thwarted a potential terrorist attack planned for Halloween weekend in Michigan and arrested multiple suspects. Director Kash Patel announced the operation on Friday after agents moved on targets in the Detroit area. Officials said there is no current threat to the public while the investigation continues.
Senior law enforcement officials briefed on the case said the suspects discussed an attack timed to Halloween, which they allegedly called “pumpkin day.” The plot included ISIS-linked elements, according to preliminary assessments. Authorities emphasized that details are still being developed as evidence is processed.
Five people from Dearborn and Inkster were taken into custody. The names have not been released because court documents remain sealed. Officials said the group had access to firearms, and investigators are reviewing devices and communications for additional leads.
What the FBI says happened
Patel said agents arrested “multiple subjects” who were allegedly plotting a violent attack over the holiday weekend. He praised federal, state and local partners and said more information will be shared when filings are unsealed.
The FBI’s Detroit office reiterated that there is no ongoing danger to schools or community events.
Officials said investigators had monitored the group for days to ensure no attack could be attempted. The timing of the arrests was chosen to remove risk around Halloween gatherings. Agents are working to determine whether the conspirators coordinated with others outside Michigan.
What is known, and what is not
Authorities have not publicly identified a specific target, a chosen method or a concrete timeline. Investigators are examining whether the group was self-radicalized or whether it had meaningful contact with external facilitators. Those findings typically emerge after forensic analysis of phones, computers and social media accounts.
Federal officials confirmed that the suspects had access to guns. It is not yet clear whether any explosives, precursor chemicals or detailed plans were recovered. Charging decisions will follow once the evidence review is further along.
State and local response
Michigan Gov. Gretchen Whitmer said she was briefed on the case and thanked the FBI and the Michigan State Police for swift action that protected residents. Attorney General Dana Nessel said state authorities are in consultation with federal partners.
The Dearborn Police Department confirmed that federal operations occurred in the city on Friday morning and told residents there was no threat to the public.
Local leaders urged calm and asked residents to remain attentive as the holiday weekend begins. School districts and city departments said they would maintain normal schedules while staying in close contact with law enforcement.
How the investigation unfolded
Officials said the FBI used a mix of physical surveillance and court-authorized collection to track the group’s activity in the greater Detroit area.
Joint Terrorism Task Force partners coordinated operational timing through standard deconfliction systems. The arrests and searches were designed to preempt any move to act during crowded weekend events.
Analysts cautioned that early narratives can shift as evidence is processed. In similar cases, agents reconstruct planning to distinguish online rhetoric from operational steps. Indicators can include weapons acquisition, site scouting and attempts to obtain explosive materials.
