Chaos unfolded at a Walmart in Michigan after a man burst into the store during a calm shopping afternoon and stabbed 11 people at random, authorities say. The attack on Saturday left six victims in critical condition and a suspect in custody.

Stabbing suspect Bradford James Gille was subdued within minutes with the help of bystanders, authorities said.

After nearly a dozen people were stabbed at a Walmart in Traverse City, Michigan, Saturday afternoon, the quick actions of a couple of Marines and other bystanders helped stop the attacker from causing further harm.
