Some protesters erupted in anger after the announcement that Officer Darren Wilson won’t be indicted in the shooting death of 18-year-old Michael Brown. Protesters overran a barricade and taunted police. Some chanted “murderer” and others threw rocks and bottles.

The windows of a police car were smashed and protesters tried to topple it before it was set ablaze. Officers responded by firing what authorities said was smoke and pepper spray into the crowd. St Louis County Police later confirmed tear gas also was used.

Some in the crowd tried to stop others from taking part in the violence.
