AT least 11 people have been injured in a horror knife attack at a Michigan Walmart.

A 42-year-old suspect has been taken into custody following the shocking incident in Traverse City on Saturday.

The 11 victims are being treated at a nearby hospital, medical authorities have announced.

“As a result, our Emergency Department is currently experiencing a higher-than-usual volume of patients,” Munson Medical Centre posted on social media.

Grand Traverse County Sheriff Michael Shea revealed at a news conference that cops believe the suspect acted alone.

“There is no information indicating there were additional suspects,” he said.

“It appears that these were all random acts.”

Shea told reporters that the suspect is a Michigan resident and had wielded a “folding knife style weapon”.

The sheriff said that three of the victims are undergoing surgery.

Six of the victims are male and five are female, he further revealed.

There was “citizen involvement” in getting the suspect into custody, Shea added.

The suspect is not believed to have been injured.

Michigan Governor Gretchen Whitmer posted on X: “I’m in touch with law enforcement about the horrible news out of Traverse City.

“Our thoughts are with the victims and the community reeling from this brutal act of violence.

“I am grateful to the first responders for their swift response to apprehend the suspect.”

FBI Deputy Director Dan Bongino said the bureau’s personnel are responding to provide any necessary support to local authorities.

Traverse City is located around 140 miles north of Grand Rapids and 255 miles northwest of Detroit.

Former Transportation Secretary Pete Buttigieg, whose husband is from Traverse City, posted on X: “Along with the whole Traverse City community, Chasten and I are shaken by the awful and senseless violence at Walmart earlier today.

“We’re thinking of everyone affected and hoping and praying for speedy recovery for all those who were injured.”

Walmart corporate spokesperson Joe Pennington told CNN: “Violence like this is unacceptable.

“Our thoughts are with those who were injured and we’re thankful for the swift action of first responders.

“We’ll continue working closely with law enforcement during their investigation.”
