In Cambridge Massachusetts, this series of attacks occurred on a busy street at mid-day. One man describe his attack like this:
...a man told officers he was walking towards Central Square when the suspect walked directly towards him. He stepped to his left and the suspect mirrored that move. He stepped to his right and the suspect moved into his path once again. When the suspect was close enough, he punched (the victim) at least twice in the eye with a closed fist, knocking him to the ground...One of the other attacks can be viewed in the security footage shown in the video at the link.
