Absolutely sickening eyewitness report:
He was at a pub with some mates, decided to leave and get something to eat at around 10pm. Walks in the direction of London Bridge, passing under the train bridge. He saw someone who had been stabbed, then saw 3 "Muslim guys" running up, started stabbing a girl. They then stabbed someone else.
He then started shouting at everyone to run, went back towards the Borough. They then stabbed the bouncer at the Tavern (pub). They were running in all the pubs, bars, stabbing everyone.
