Police say 20 people were arrested during the protest in East Liberty on June 1, when police admitted to using tear gas.

Police said smoke canisters were used to disperse the crowd at Centre and Negley and that tear gas was used in other parts of East Liberty after repeated orders were given for the group to disperse.

Meanwhile, the Pittsburgh Police Citizen Review Board has launched an investigation into how these protests were handled by officers.

The Allegheny County DA withdrew charges in 22 cases connected to the East Liberty protests.

The DA says none of the cases in which charges were withdrawn involve any violence or property damage.
