Protesters clash with Police in Philedelphia

Philadelphia

"A protest started Thursday afternoon in front of city hall. Aerial video showed several hundred people gathered. As the crowd swelled, it moved toward Rittenhouse Square.

Police and protesters clashed about 7:45 p.m., apparently when the group tried to block the entrance to I-95. CNN's Poppy Harlow reported police had said they would move against anybody who tried to do that.

Aerial video showed uniformed officers grouping to push back demonstrators, many who held their hands in the air and chanted, "Hands up."

According to tweets from CNN's Lawrence Crook, protesters sat down in the middle of Broad Street, blocking traffic. Some protesters were arrested. Later the crowd marched to the federal prison building and chanted, "You are not alone."

Harlow said inmates in the prison flicked their lights on and off in recognition." CNN
