A potential terror attack the FBI said it thwarted in Michigan ahead of Halloween weekend had a connection to ISIS, Fox News has learned.

A top federal law enforcement source told Fox News earlier Friday that the attack plot was tied to international terrorism, but more information was not immediately available.

The FBI said Friday that it prevented a potential terrorist attack in Michigan, arresting multiple suspects accused of plotting violence over the Halloween weekend.

“This morning, the FBI thwarted a potential terrorist attack and arrested multiple subjects in Michigan who were allegedly plotting a violent attack over Halloween weekend,” FBI Director Kash Patel posted on X.

“More details to come,” Patel wrote. “Thanks to the men and women of FBI and law enforcement everywhere standing guard 24/7 and crushing our mission to defend the homeland.”

In a statement to Fox News, Patel said the FBI’s quick response prevented a potentially tragic situation from unfolding.

“Through swift action and close coordination with our local partners, a potential act of terror was stopped before it could unfold,” Patel said. “The vigilance of this FBI prevented what could have been a tragic attack — and thanks to their dedication, Michigan will have a safe and happy Halloween.”

FBI Deputy Director Dan Bongino also praised the reported operation, calling it an example of proactive law enforcement that saves lives.

“This is what real law enforcement looks like — proactive, relentless, and focused on saving lives,” Bongino said in a statement to Fox.

“Our agents and partners in Michigan acted fast, followed the evidence, and stopped a threat before anyone got hurt. Under the leadership of Director Patel and the watch of this FBI, America is a safer place.”

Bongino also posted on X, writing: “Protecting the Homeland is our top priority. We will not rest.”

“As a retired FBI agent, I can tell you that cases like the one in Michigan highlight how these investigations are carefully built over time and why they are so important to public safety,” Jason Pack, a retired FBI Supervisory Special Agent, told Fox News Digital. “The FBI often becomes aware of potential threats through a tip from the public, a local police partner, or activity observed on online platforms where individuals share violent or extremist ideas.”

“When someone independently expresses a desire or plan to harm others, the bureau may use undercover agents or trusted sources to engage that person in a controlled setting… Agents are trained to avoid any actions that could be considered entrapment, and all undercover operations follow strict oversight and legal guidelines,” Pack added.

Pack said that, following this morning’s arrests, agents are likely executing search warrants to collect more evidence.

The Detroit Public Affairs Office confirmed to Fox News that members of the FBI field office in Michigan were in Dearborn and Inkster this morning, but there is no clear indication if this was connected to the thwarted attack.

News of the thwarted plot comes 10 months after Shamsud‑Din Jabbar plowed a pickup truck into New Year’s revelers on New Orleans’ Bourbon Street. Fifteen people were killed and dozens were injured, making it one of the deadliest acts of terrorism in the U.S. since 9/11. 

Jabbar’s truck carried an ISIS flag and the FBI said he was inspired by the terror group.
