Two thugs who posed as good Samaritans in one of the most notorious crimes of the 2011 London riots face jail after robbing a defenceless Malaysian student.

Ashraf Rossli, 21, had been in Britain for just a month when he was knocked to the ground and left a bloodied mess on August 8 last year.

Moments after his jaw was smashed and his bicycle stolen, John Kafunda, 22, was caught on camera lifting him up and appearing to shepherd him from trouble.

But seconds later he and Reece Donovan, 22, began rifling through his rucksack as the victim's back was to them. They robbed him of a portable Playstation and 10 games.
