‘You ain’t no Muslim, bruv’: One Londoner’s perfect put-down of knife attacker goes viral

YouAintNoMuslimBruv became Britain’s top trending Twitter hashtag after video emerged of a passer-by shouting the scornful remark at a knife-wielding man in a London Underground station.

Police are treating Saturday’s attack at Leytonstone Tube station in east London as a “terrorist incident”.

In video footage, an onlooker is heard shouting in a thick East London accent “You ain’t no Muslim, bruv” as the 29-year-old suspect, reeling after being hit with an electric stun gun, is pinned down and handcuffed.
