More Violence as Curfew is Implemented in Ferguson (Video)

FERGUSON, Mo. (AP) — The first night of a state-imposed curfew in Ferguson, Missouri, ended with tear gas and seven arrests, after police dressed in riot gear used armored vehicles to disperse defiant protesters who refused to leave a St. Louis suburb where a black, unarmed teen had been shot by a white police officer a week earlier.

Missouri State Highway Patrol Capt. Ron Johnson said protesters weren’t the reason for the escalated police reaction early Sunday morning after the midnight curfew took effect, but a report of people who had broken into a barbecue restaurant and a man who flashed a handgun in the street as armored vehicles approached the crowd of protesters.

Also overnight, a man was shot and critically wounded in the same area, but not by police; authorities were searching for the shooter. Someone also shot at a police car, officials said.

U.S. Attorney General Eric Holder has asked for the Justice Department to arrange an autopsy on the body of Michael Brown by a federal medical examiner.

Justice Department spokesman Brian Fallon said in a news release on Sunday that Holder asked for the additional autopsy because of the “extraordinary circumstances involved in this case” and at the request of Brown’s family.

The 18-year-old Brown was shot and killed by a Ferguson, Missouri, police officer on Aug. 9. Brown was black and unarmed. Officer Darren Wilson is white.

Fallon says the autopsy will take place as soon as possible.
