Most of the youth gathered peacefully, but as the night went on tensions escalated. Scattered fights broke out among the youth. Some tried to smash storefront windows, police said. Some walked in the middle of Pratt Street and blocked traffic. A half-dozen youths took a bicyclist to the ground and beat him. One teen jumped on the roofs of two parked cars. Another randomly kicked a passerby in the face, according to a video compiled and distributed by Baltimore Police.
