Beau Isagba, now 18, was last month found guilty of the attack, which has become a symbol of the riots after a video of the student's ordeal was by millions around the world on YouTube. Isagba punched 20-year-old Mr Rossli before stealing his bicycle. As the victim slumped bleeding to the pavement, clutching his jaw, a gang posing as "Good Samaritans" then rifled through his rucksack before fleeing. On Friday a judge sentenced Isgaba to a total of 84 months for the attack and other convictions including carrying a blade and cannabis possession. While sentencing him, the judge said Isgaba represented the "worst aspects" of society. Jailing him at Wood Green Crown Court in north London, Judge Witold Pawlak said: "You represent the worst aspects. On the 8th of August you behaved like a thug, and without any compassion.
