Police in Dearborn, Michigan, confirmed FBI operations had been conducted in the area, without offering details.

The Federal Bureau of Investigation (FBI) in the United States has announced that it disrupted an alleged “terrorist attack” in the northern state of Michigan.

Few details were released about the operation or the suspects involved. In a social media post on Friday, FBI Director Kash Patel pledged to reveal more information later on.

“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,” he 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.”

Patel did not specify which part of Michigan the FBI operation took place in. But in a separate social media post on Friday, the police department for the city of Dearborn noted that FBI agents had been active in its community.

It is unclear whether their presence pertained to the same operation or a different one.

“The Dearborn Police Department has been made aware that the FBI conducted operations in the city of Dearborn earlier this morning,” the department wrote. “We want to assure our residents that there is no threat to the community at this time.”

Located in southeast Michigan, near Detroit, Dearborn is known as the headquarters for the Ford Motor Company, and it is the first city in the US to have an Arab American majority.

The Detroit Free Press, a Michigan newspaper, reported there were also FBI operations in Inkster, another suburb of Detroit.

This is a developing story. More details to come.
