Protesters march down the middle of a street Friday in front of a convenience store that was looted and burned following the shooting death of Michael Brown by police nearly a week ago in Ferguson, Mo.

FERGUSON, Mo. — Anger spurred by the death of a black teenager at the hands of a white police officer boiled over again when protesters stormed into a Missouri convenience store — the same store that Michael Brown was accused of robbing.

Police and about 200 protesters clashed in Ferguson, Mo., late Friday after another tense day in the St. Louis suburb, a day that included authorities identifying the officer who fatally shot Brown on Aug. 9. At the same news conference in which officer Darren Wilson was named, Ferguson Police Chief Thomas Jackson released documents alleging Brown stole a $48.99 box of cigars from the convenience store, then strong-armed a man on his way out.

Just before midnight, some in what had been a large and rowdy but mostly well-behaved crowd broke into that same small store and began looting it, said Missouri State Highway Patrol Capt. Ron Johnson.

Some in the crowd began throwing rocks and other objects at police, Johnson said. One officer was hurt but details on the injury were not immediately available.

Johnson said police backed off to try and ease the tension. He believes looting may have spread to a couple of nearby stores. No arrests were made.

“We had to evaluate the security of the officers there and also the rioters,” Johnson said. “We just felt it was better to move back.”

Meanwhile, peaceful protesters yelled at the aggressors to stop what they were doing. About a dozen people eventually blocked off the front of the convenience store to help protect it.

Brown’s death had previously ignited four days of clashes with furious protesters. Tensions eased Thursday after Gov. Jay Nixon turned oversight of the protests over to the Missouri Highway Patrol. Gone were the police in riot gear and armored vehicles, replaced by the new patrol commander who personally walked through the streets with demonstrators.

Nixon appointed Johnson to take over security after concerns were raised about how local police had used tear gas and rubber bullets on protesters earlier in the week. Johnson said one tear gas canister was deployed Friday night after the group of rioters became unruly.

Jackson’s decision to spell out the allegations that Brown committed the robbery and his releasing of surveillance video angered attorneys for Brown’s family and many in the community, including U.S. Rep. William Lacy Clay. Earlier Friday night, the Democratic congressman took a bullhorn and told protesters, “They have attempted to taint the investigation. They are trying to influence a jury pool by the stunt they pulled today.”
