Authorities have arrested at least two people at a protest over the Ferguson grand jury decision in which several demonstrators stormed City Hall in St. Louis.
An undetermined number of protesters made it into the building Wednesday while shouting "Shame, shame."
The protest march included several hundred people and began with a mock trial of Ferguson Officer Darren Wilson, who shot and killed 18-year-old Michael Brown. It was held on the steps of the Old Courthouse, the site of the Dred Scott trial.
More than 100 additional police officers were called to the building and it was locked down.
A total of 58 people were arrested at area protests overnight, including 45 in Ferguson.
