Brave bystander tackles London moped mugger moments after he snatched woman's bag

This is the moment a bystander tackles a suspected moped mugger moments after he snatched a handbag from a woman in North London.

Dramatic dashcam footage emerged today of two helmeted thieves on a scooter mounting a pavement to apparently snatch the black bag from the lone pedestrian in Islington.

They drive off as the stunned victim looks on in horror following the attempted mugging in Barnsbury.

Seconds later a casually dressed pedestrian charges into the scooter’s path, grabs the pillion passenger by the neck and wrestles him from the saddle.

The suspect squirmed free to rejoin his accomplice but lost the bag in the fracas.

As the have-a-go hero checks himself for injuries, the shocked driver says: “You alright mate? Don’t worry I’ve got it all on camera.”

The driver had been tailing the moped as the pair apparently prowled the streets hunting for victims.

The footage was uploaded to the internet yesterday by a user who said it took place on Sunday.

They wrote: “It was an incredible act of bravery.”

London Assembly member Sian Berry called for Scotland Yard to consider banning pillion passengers in parts of the capital such as Islington which have been badly hit by moped robberies.

Security experts have warned of a predicted rise in moped-enabled criminal activity including robbery in the run up to Christmas.
