Footage shows a man punching another man and knocking him to the ground at a Metro station in Hollywood early Tuesday morning.
The older man in a dark-colored jacket, standing near the edge of the platform, exchanging words with a younger man. Seemingly unprovoked, the younger man deals a punch in the head to the older man, who then falls to the ground near the tracks.
The attacker was accompanied by two other men, and all three left before paramedics or law enforcement arrived, as did the victim. But several others were witness to the crime.
