More protests planned after ex-officer cleared of black man's fatal shooting
Activists have vowed to hold more protests after the acquittal of a white former St Louis police officer over the fatal shooting of a black man.
Hundreds marched for hours on Friday in mostly peaceful demonstrations until a broken window at the mayor's home and escalating tensions led riot officers to fire tear gas to disperse the crowds.
Activists had for weeks threatened civil disobedience if Jason Stockley were not convicted over the 2011 death of 24-year-old Anthony Lamar Smith.
That stirred fears of civil unrest and prompted the construction of barricades around police headquarters, the courthouse where the trial was held and other potential protest sites.
More than 20 arrests were made by early Friday evening. Police reported that 10 officers had suffered injuries by the end of the night.
