London: An Indian-origin businessman was crushed under a truck as he fought a gang of robbers on the streets of London on Tuesday. Shammi Atwal tackled the gang of 10 raiders armed with a sledgehammer and metal bars at the warehouse of the drinks company he owned, Glenn & Co, in east London. He was pushed on to the road during the scuffle and run over by the truck. Scotland Yard launched a murder investigation into the death of the 44-year-old father of two, whose wife Deepa suffered minor injuries during the attack. Atwal's uncle Tarsem Singh told the Evening Standard: "He worked very, very hard and rest of the time was spent with his family or at the Sikh temple. He was a wonderful father." The gang was described as white and the Metropolitan Police appealed for witnesses to come forward.
