At least 11 people have been injured in a stabbing at a Walmart supermarket in Michigan, US authorities say.
A 42-year-old suspect was in custody following the incident in Traverse City, authorities confirmed.
A nearby hospital said it was treating 11 victims.
Footage posted online showed multiple police and ambulance units in the car park of the Walmart.
Grand Traverse County Sheriff’s Office confirmed it was investigating ‘a multiple stabbing incident at the Walmart in Traverse City’.
The suspect is a Michigan resident and used a ‘folding knife style weapon’, Sheriff Michael Shea said. The incident appeared to be a ‘random act’, he added.
He said people in the store assisted in apprehending the man and helped treat the injured.
“This was a joint effort all the way through, and, as I mentioned, the citizens, too,” Shea said of the response.
As of last night, all the 11 victims were in critical condition, BBC News reported.
FBI Deputy Director Dan Bongino said federal personnel were responding to provide any necessary support to local authorities.
Traverse City is about 410km northwest of Detroit.
