Riot police fought running skirmishes with anti-Wall Street protesters on Saturday, firing tear gas and bean bag projectiles and arresting more than 200 people in clashes that injured three officers and at least one demonstrator.
Three police officers and one protester were injured during the clashes, the city said, without detailing their conditions. Internet broadcasts by activists showed several demonstrators being treated by paramedics or loaded into ambulances.
The scuffles erupted in the afternoon as activists from the Occupy movement sought to take over a shuttered downtown convention center, sparking cat-and-mouse battles that lasted well into the night in a city that has seen tensions between police and protesters boil over repeatedly.
