This is pretty disgusting. The thug didn't even steal anything. terrible.
A teenage girl said she had "no idea" what happened after an apparent unprovoked attack left her motionless on a sidewalk in east London.
"The next thing," she knew, she was in an ambulance, according to the UK's Daily Mail.
In shocking footage caught on surveillance tape, a man is seen following the unknowing 16-year-old victim before knocking her unconscious with a single blow to the head, a chilling attack that saw the girl crumble to the pavement in broad daylight.
