text: Protests to demand answers in the case of Freddie Gray, the 25-year-old black man who died in Baltimore Police custody last week, descended into chaos on Saturday night. After a few hours of peaceful demonstrations, scores of rowdy protesters crowded outside Camden Yards, where the Baltimore Orioles beat the Boston Red Sox in ten innings. Spectators at the game, with a reported attendance of 36,757, were told that they could not leave the baseball stadium until cleared to do so by police, who allowed them to exit shortly after 10pm when the game ended. Outside, protesters threw objects at cars, kicked windshields, smashed windows and threw a flaming trash can at police in riot gear. Multiple demonstrators were seen jumping on police cars. A civilian car's windshield was also shattered as chants of 'shut it down' were heard during unrest that started around 6.30pm. Violence continued into the evening, with reports of looting and smashing of shop windows despite Baltimore Police Commissioner Anthony Batts's  order for protesters to disperse.
