A martial arts expert and journalist was in intensive care after stepping in to break up what he believed to be a fight, which turned out to be the terror attack in Borough Market.
Geoff Ho, who is a business editor at the Sunday Express, was stabbed in the throat after he tried to protect a bouncer on the door of the Southwark Tavern.
Friends spoke of desperately trying to find him after hearing he had been stabbed. One said she thought Mr Ho would have "stood up and been counted because he's just that type of person".
In a Facebook post about the incident, he wrote: "Don't know whether it was stupid or noble to jump and break up the fight outside the Southwark Tavern, but two a*******s trying to do over the lone bouncer on the door isn't happening on my watch."
