Los Angeles police responded Sunday after someone drove a U-Haul box truck down a street crowded with demonstrators in support of the Iranian people, causing protesters to scramble out of the way and then pursue the speeding vehicle to try to attack the driver. The U-Haul truck, with its side mirrors shattered, was stopped several blocks away and surrounded by police cars. ABC7 news helicopter footage showed officers keeping the crowd at bay as demonstrators swarmed the truck, throwing punches at the driver and thrusting flagpoles through the driver’s side window. The police department confirmed its officers were on scene but didn’t confirm if any arrests were made. Two people were evaluated by paramedics and both declined treatment, the Los Angeles Fire Department said.
