ST. LOUIS — Protests turned violent for a second night near St. Louis following the acquittal of a white former police officer in the fatal shooting of a black man, as a small group of demonstrators refused to disperse, breaking windows at dozens of businesses and throwing objects at police, who moved in with hundreds of officers in riot gear to make arrests.

The confrontation took place late Saturday night in the Delmar Loop area of University City, a suburb about 10 miles west of St. Louis near Washington University. The area is known for concert venues, restaurants, shops and bars, and includes the Blueberry Hill club, where rock legend Chuck Berry played for many years.
