Eleven people were injured in a “random” stabbing by a suspect with a folding knife-style weapon at a Walmart in Traverse City, Michigan, Saturday, according to the Grand Traverse County Sheriff’s Office.

The total number of injuries was not immediately clear, nor was it clear whether there were multiple suspects.

Shoppers fled for their lives after a suspect brandished a knife inside the Walmart Supercenter on Crossing Cir, Traverse City, in Michigan.
