Authorities say one person was shot and critically wounded and seven people were arrested as police used smoke and tear gas to impose a curfew in a St. Louis suburb where a black teen walking down the street had been shot by a white police officer.

Missouri State Highway Patrol Capt. Ron Johnson says his department's strong response early Sunday morning came after a midnight to 5 a.m. curfew took hold in Ferguson, and was precipitated by two events.

Johnson says concerns about people who'd broken into a barbecue restaurant and taken position on the roof overlooking approaching police was one concern. He says another concern involved a man flashing a handgun appeared in the middle of the street as armored vehicles approached.

Johnson says someone also fired at a patrol car, but no officers were injured.

Eighteen-year-old Michael Brown was shot Aug. 9, prompting protests, unrest and claims of civil rights violations.
