Mumbai, June 9 -- A 26-year-old delivery rider was killed, and six others were injured after an electric BEST bus ploughed into five vehicles near Plaza Cinema in Dadar on Monday morning. The accident took place around 9.30 am, when the driver of the e-bus, Vikas Padave, operating on route A-463 (Dharavi Depot to Plaza Cinema) lost control over the vehicle and crashed into a kaali-peeli taxi, two scooters and two private cars, police said. The deceased was identified as Niyaz Ahmed Shaikh, 26, a delivery rider from Null Bazaar. Police said the bus rammed his scooter from behind, causing him to fall beneath the vehicle, which dragged him several metres. He was declared dead at Sion Hospital. Among the injured, 22-year-old student and part-time delivery rider Vrishabh Gupta is in critical condition. The accident has put the spotlight back on BEST's wet-lease operations, with authorities probing the driver's claim that the electric bus suffered a brake failure moments before it ploughed into five vehicles. BEST has constituted a four-member committee of senior officers to probe the case.P4...
