A knife attack occured on Saturday night in Leytonstone underground station in East London. According to witnesses, the 29-year-old assailant wounded three people, one seriously, and shouted "this is for Syria" during the attack. Police used a stun gun to detain him.
After the attack some people took to Twitter using the #YouAintNoMuslimBruv hashtag to protest against attackers who try to misuse Islam to justify attacks on unarmed civilians.
"#YouAintNoMuslimBruv, just another psychopath attempting to use religion as an excuse to justify your barbaric actions!!" said one Twitter user, Natasha.

"This kind of support has helped to ally a lot of people with the Muslim community who feel that that comment in itself summarizes what Muslims feel in Britain," Muslim Association of Britain President Omer El-Hamdoon told Anadolu Agency.
British Prime Minister David Cameron said in a press conference, "Let me also pay credit to the person - you can't quite see who it is from the film - who made that brilliant statement about 'you ain't no Muslim'."
"Some of us have dedicated speeches and media appearances and soundbites and everything on this subject, but 'You ain't no Muslim bruv' said it all much better than I ever could. Thank you, that will be applauded around the country," he added.
Londoners embraced the phrase. Twitter user Matthew Harper wrote, "#youaintnomuslimbruv is the most #London response to terrorism you could imagine and pretty much sums up how we all feel about these maniacs."
