TRAVERSE CITY, Mich. (AP) — 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.

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.
