'You ain't no Muslim bruv' stab witness 'had to voice his feelings'

The man who shouted at a suspected terrorist during a stabbing at a Tube station, coining a phrase that later went viral, has told how he just had to say what he felt at the time.
The bystander was heard in video footage of the incident at Leytonstone underground station in east London last weekend, shouting “You ain’t no Muslim bruv” as an attacker wielding a knife stabbed a man.
