AN 11-year-old judo star was burnt alive after he was ‘doused in petrol’ and locked in a shed that was set on fire by ‘envious’ older children. Albert Umbetyarov was trapped in a shed in woods in the Dubovaya Roschcha region of Moscow after an argument on Friday, Russian investigative authorities confirmed. A witness told Argumenti that attackers had ‘used bats to beat him almost unconscious’ before ‘dousing him in petrol’, and locking him in a shed they set on fire. The attackers were reportedly aged 13 to 15, and the horror captured on camera by a group of girls who were said to have uploaded the footage and streamed it online. Another witness said Albert was attacked ‘out of envy’ as a successful Judo athlete who ‘was doing better than them’
