Protesters force lockdown of City Hall in St. Louis

Several people protesting the Ferguson grand jury decision stormed into City Hall in St. Louis on Wednesday, leading police to lock down the building and to call in more than a hundred additional officers.

At least two people were arrested after the incident, in which the protesters shouted "Shame, shame" while rushing into the building.

Those who made it inside City Hall were part of a group of about 300 protesters who marched and held a mock trial of Darren Wilson, the Ferguson police officer who shot and killed 18-year-old Michael Brown during an Aug. 9 confrontation in the St. Louis suburb. (AP)
