Multiple people who had been allegedly plotting a violent attack over the Halloween weekend were arrested on Friday in Michigan, FBI Director Kash Patel said in a social media post. The law enforcement effort was focused on suburban Detroit. Patel said more information would be released later. Investigators believe the plot was inspired by Islamic State extremism and are investigating whether those in custody were potentially radicalised online, according to two people briefed on the investigation who could not publicly discuss details. They spoke to The Associated Press on condition of anonymity. FBI and state police vehicles were in a neighbourhood near Fordson High School in Dearborn. People wearing shirts marked FBI walked in and out of a house, including one person who collected paper bags.
