ATLANTA (AP) — Crews were repairing damage to some businesses in downtown Atlanta on Wednesday, a day after protesters filled the streets in mostly peaceful opposition to the Ferguson, Missouri, grand jury decision.

Authorities said some in the group broke windows and 21 people were arrested in Tuesday night's demonstration.

Police Chief George Turner said most arrests were for failure to disperse when asked, but one person faces a weapons charge. They were protesting the decision not to indict the police officer who fatally shot an unarmed 18-year-old in Ferguson.

Some protesters tried to block the interstate where it meets downtown, and the chief said windows were broken at the Wells Fargo branch and Mehan's Irish Pub.

The police chief said windows in a patrol car and a taxi also were shattered.
