NEW DELHI: Four juvenile passengers stabbed a 26-year-old auto driver to death on Kasturba Gandhi Marg, near Connaught Place, late on Sunday after the driver asked them to pay Rs 20 extra per head as night charge — a total of Rs 80.The boys were heading to CP from Khanpur but got into an argument with the driver on the way over the extra charge, police said. One of them allegedly whipped out a button knife and stabbed the driver, identified as Jahangir Alam , in the chest at KG Marg. All four have been arrested.As Alam slammed the brakes, the juveniles dragged him out and kicked him on the stab wound. They fled when people started gathering at the spot. Despite his injuries, Alam got back on the auto and drove towards CP looking for a cop. He found one down the road and collapsed after telling him about the attack, police said.The cop, head constable Rakesh, called up the control room around 11.40pm. As they waited for a police vehicle, passersby started making videos of Alam. One such clip that went viral shows the video-taker questioning Alam about who stabbed him. Alam is seen struggling to speak and keeps gasping for breath in the 44-second video.Alam died during treatment at Ram Manohar Lohia hospital around 12.30am. He was identified with the help of his licence, cops said. Meanwhile, the accused had fled the spot, heading towards Balwant Rai Mehta lane. After driving a hired three-wheeler for some time, Alam had bought his own auto less than two months back, and was paying an EMI of Rs 15,000, police said.Police said Alam had come from a village in West Bengal and had been living in the capital with his wife and four children. Four months back, he had sent his family back to the village in view of the rising cost of living in Delhi. Alam was set to visit his family at the end of the month and had bought train tickets. As it turned out, it’s the family that is now coming to Delhi to take his body home.DCP (New Delhi) Madhur Verma said all four accused juveniles had been apprehended and the cops would push for them being treated as adults. A case under sections 302 (punishment for murder) and 34 (common intention) of the IPC and Arms Act has been registered. Cops said the accused boys had boarded the auto from Khanpur around 11pm and asked Alam to take them to CP. Before they hopped onto the vehicle, they had decided on Rs 120 as the fare. But as they were approaching CP, Alam told them that as it was pos 11pm, they would be charged Rs 20 extra, per head. He had earlier told them that he was allowed to take just three passengers but the boys insisted.Agitated by the demand for more money, the boys started arguing with Alam. One of the juveniles pulled out a button knife. Before Alam could react, the juvenile leaned forward and stabbed him in his chest.
