A four-year-old boy was killed after the two-wheeler he was travelling on with his family was knocked down by a speeding car near Mambakkam. A senior official of the Tambaram Police Commissionerate said Mukundan (42), a resident of Ponmar near Kelambakkam, was riding his two-wheeler from Mambakkam towards Ponmar bringing back Sushanth, a kindergarten student, and his twin sons from school on Thursday (August 6, 2026). As they approached Mambakkam, a speeding car coming from the opposite direction collided with the motorcycle, throwing all four of them onto the road. Sushanth, who was seated in the front, sustained a severe head injury and died on the spot. The others, including Mukundan, suffered minor injuries and were rushed to a private hospital. The Pallikaranai Traffic Investigation police, on being alerted, sent the body of the boy to the Tambaram Government Hospital for post-mortem examination. The police officials are on the lookout for the car that caused the accident and fled the scene. Published - August 07, 2026 03:04 pm IST
