Moped gang 'armed with knives' attack Amir Jewellery Maida Vale north London ...

Shocking footage captures the moment a knife-wielding moped gang carry out an armed raid on a London jewellery shop.

Dressed in black and riding scooters, the group of men were seen pulling up outside Amir Jewellery in Maida Vale, north London, before smashing their way into the shop.

Members of the public desperately chased two of the attackers who were on foot as they brandished foot-long machetes this afternoon. 

One managed to tackle a man to the floor before police came to arrest him. Two others were detained by armed police at Camden Market two miles away. 

A video posted online shows the robbery unfold as a panicked 999 caller says: 'Hello, burglary at Maida Vale Road Amir Jewellery, quickly they have a knife!

'They went inside they have a knife they're attacking people.'
