People are rallying around this hashtag after a 'terrorist incident' at a London underground station
Following a terrorist incident at a London underground station - in which three people were stabbed by a man reportedly screaming "this is for Syria" - people have rallied around the hashtag #YouAintNoMuslimBruv.
It started trending after a man was filmed telling the suspected attacker - who was still being questioned by police on Sunday morning - "you ain't no Muslim bruv."
