A pickup truck drove through an intersection where protesters were demonstrating Saturday in Tallahassee, Florida, causing people to run screaming out of the way as the vehicle stopped and started.
At one point, the truck had a person on its hood, according to witnesses and video posted on social media.
Tallahassee Mayor John E Dailey tweeted later the driver was taken into custody after hitting the crowd at a low speed. He says no one was seriously injured.
Video shows the truck stopped at a traffic light, and protesters walking around and near it while appearing to speak to the driver. The truck then suddenly accelerates.
