LONDON - Ordinary Londoners demonstrated 'breath-taking heroism' in disarming a knife-wielding attacker who injured several people in Friday's incident at London Bridge, mayor Sadiq Khan said. 'What's remarkable about the images we've seen is the breath-taking heroism of members of the public who literally ran towards danger not knowing what confronted them,' Khan told reporters, adding that man had been wearing a fake bomb. 'Members of the public didn't realise at the time that was a hoax device, and they really are the best of us,' Khan added.
