ST. LOUIS (AP) — A prominent young protester who serves on Missouri’s Ferguson Commission has been charged with assault stemming from a protest at St. Louis City Hall.

Twenty-two-year-old Rasheen Aldridge was among a group of young activists who met with President Barack Obama at the White House Monday. The St. Louis Post-Dispatch reports that Aldridge was one of three demonstrators charged Thursday with misdemeanor assault.

The Forest Park Community College student was among several hundred demonstrators who marched to City Hall last week as part of a protest over a St. Louis County grand jury’s decision to not indict Ferguson police officer Darren Wilson in Michael Brown’s shooting death.

Several participants stormed the entrance of the building, which was quickly locked down. Police used pepper spray to disperse the crowd.
