WATCH: Thugs rob man, 20, on one of UK's swankiest streets

THIS is the ghastly moment two robbers ambush a young man in on one of Britain's poshest streets.

The 20-year-old victim can be seen walking down a mews-style road and under an arch when one man races after him from behind.

Thug number one chokes the unsuspecting lad around the neck and drags him to the side of the lane.

A second robber meanwhile can be seen racing after the pair – but not to help the victim – but to rifle through his pockets for his phone and wallet.

The duo let the man crash to the ground and leave him crumpled in shock as the they sprint back the way they came.

   SUDDEN: In a matter of seconds the pair execute the robbery

   HELPLESS: The man is trapped by the attackers

   DEFEATED: The victim lies on his back a beaten man
