11 People Injured in Knife Attack in Michigan

At least 11 people have been injured in a knife attack at a Walmart supermarket in Michigan, authorities said on Sunday.

Authorities added that a suspect was in custody following the attack in Traverse City.

 Munson Medical Centre said on social media that it treated 11 victims. "As a result, our Emergency Department is currently experiencing a higher-than-usual volume of patients,". Local media reports said three people were undergoing surgery.

Grand Traverse County Sheriff's Office confirmed it was investigating "a multiple stabbing incident at the Wal-Mart in Traverse City".

The suspect is a Michigan resident and used a "folding knife style weapon", Sheriff Michael Shea told reporters. The incident appeared to be a "random act", he added.

Michigan Governor Gretchen Whitmer said she was "in touch with law enforcement about the horrible news".

"Our thoughts are with the victims and the community reeling from this brutal act of violence," she added.
