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

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.

Michigan authorities said Sunday they are seeking to file terrorism charges and 11 charges of assault with intent to murder against a 42-year-old man accused of carrying out a knife attack at a Walmart store.
