Video footage from the scene of a stabbing at Leytonstone station in east London on Saturday night has birthed a hashtag of defiance across social media.
Following what the Metropolitan Police are treating as a "terrorist incident" - in which a man was Tasered and arrested after reportedly threatening Tube passengers with a knife - a video from the scene has struck a chord with Londoners online.
According to reports, the suspect shouted "this is for Syria" before lashing out at commuters in the ticket hall of Leytonstone station at 7pm on Saturday.
Footage recorded by rapper Big Tobz, sees an onlooker shouting "You ain't no Muslim, bruv" as police detained the suspected attacker, sparking Twitter users to adopt the cry as an act of defiance against "terrorism".
"You ain't no Muslim, bruv" is a wonderfully British cry of defiance. #Leytonstone— Stephen Daisley (@JournoStephen) December 5, 2015

#YouAintNoMuslimBruv Only calling the attacker a cad and bounder would have been more British.— Johnnie Hales (@NorfolkMiniOC) December 6, 2015
