beanbag non-lethal rounds after a protester threw a garbage can at officers. During the raid police arrested a total of 75 people, mostly for misdemeanors. Police erected metal barricades around the perimeter of the encampment, as 200-300 protesters gathered around them chanting. At 4 p.m. between 1000 and 1500 protesters gathered at the downtown Oakland Public Library for a rally and march back to the plaza to try and re-occupy the plaza. On their way, they headed to the Oakland Police Department Headquarters to protest, and were blocked by a line of police in riot gear. There was a brief standoff and after a police officer attempted to arrest a woman, 50 or so protesters surrounded the officers and some protesters threw paint on the police. At 6 p.m. riot police began firing tear gas at the marching protesters. The protesters continued to regroup and, at one point, sat down with linked arms in the intersection of 14th and Broadway near the plaza. The protest was declared an unlawful assembly and protesters told to leave or be subject to arrest The march continued around the city until about 9:30 p.m. when the protesters returned again to the plaza which was barricaded and guarded by 100 police officers in riot gear. Some protesters threw water bottles and other objects at the police after which police issued dispersal orders, which failed to disperse the crowd. Police then fired tear gas and beanbag rounds at some remaining protesters. Oakland police chief Howard Jordan denied the use of flashbang grenades and said that the explosions came from M-80 firecrackers thrown by protesters. There were conflicting reports between protesters and police over whether the loud noises and explosions came from flashbang grenades or M-80 firecrackers One protester, Iraq War veteran Scott Olsen, suffered a skull fracture caused by a projectile that witnesses believed was a tear gas or smoke canister fired by police. He was rushed to the hospital by other protesters, who were struck with unknown projectiles while attempting to aid him. At least two other protesters were also injured. The American Civil Liberties Union and National Lawyers Guild called for an investigation into the use of alleged use of excessive force by some Oakland police officers.
