Five men have been arrested after a group of moped riders raided Amir Jewellers in Maida Vale.
Dressed in black and riding scooters, the group of men were seen pulling up outside Amir Jewellery in Maida Vale.
Police say they were armed with knives, a hammer and a crowbar.
The raid took place at about 17:10 BST on Monday.
Members of the public desperately chased two of the attackers who were on foot as they brandished foot-long machetes.
Footage on social media appears to show members of the public attempting to stop the group.
