Fresh footage shows a lunchtime robbery at a luxury London jeweller store on Thursday in which a "have a go hero" city worker attempts to tackle one of the masked robbers.
Three men, dressed all in black, had attacked Carr Watches and Diamonds with sledgehammers, before making off on mopeds. But one got left behind - at which point an unidentified man in a suit attempted to take him down.
The Evening Standard got a hold of camera footage of the drama. Here are the highlights:

An eyewitness told the Standard that it was "like something out of a Hollywood movie. The next thing a smartly dressed man tried to tackle one of the robbers but was then threatened with a massive machete. We were all looking on in total shock and horror, it did not last long but everything was total chaos."
"The man who tried to stop them was a real have a go hero," they added. "He could have been killed. He looked tough but when you are against a machete you have no chance. At least he slowed them down though."
The machete-wielding suspect was arrested later that day, in an underground car park. The other two remain at large.
