Innocent commuter is strangled with a scarf until he passes out in unprovoked attack

An innocent commuter was strangled with a scarf until he passed out by a fellow bus passenger in an unprovoked attack. CCTV footage released by police shows a man using his scarf to choke the 37-year-old victim, who was making his way to work in the Earls Court area of London. It shows the passenger, who police say has been left 'highly traumatised' by the incident, losing consciousness briefly before coming around, at which point the suspect can be seen trying to strangle him once again.
