MUMBAI, May 21 -- Six days after a 52-year-old BEST bus conductor was crushed to death in a four-bus chain collision in Andheri West, a 26-year-old accountant died after falling off a motorcycle and coming under the rear wheel of a BEST bus in Andheri East on Tuesday evening. The deceased, identified as Ayesha Salmani, was riding pillion on a motorcycle driven by her colleague, Ashutosh Singh, 28, when the accident occurred on Marol Maroshi Road near Sakinaka, shortly after the two left their office around 7pm. According to the MIDC police, CCTV footage from the spot showed the motorcycle skidding after Singh allegedly lost control while applying sudden brakes. Salmani fell to the right side of the road and was run over by the rear tyre of a BEST bus approaching from behind. Police said Singh escaped with minor injuries. "The bus driver could not react in time as the woman fell suddenly onto the road. He realised what had happened only after bystanders signalled him to stop. The driver did not flee the spot," an officer from MIDC police station said. Investigators said the road stretch where the accident occurred does not have a divider. Preliminary inquiries revealed that Singh allegedly applied emergency brakes after a pedestrian suddenly attempted to cross the road. "Witnesses told us that the biker lost balance after braking abruptly. While the rider fell towards the left side, the woman fell to the right and came under the rear wheel of the bus," the officer added. Following an analysis of CCTV footage and witness statements, MIDC police arrested Singh for negligence. He was later released on bail. An FIR was registered under sections 106(1) (causing death by negligence) of the BNS. The incident comes close on the heels of another fatal BEST-related accident reported on May 14 in Andheri West, where BEST conductor Shekhar Baburao Rawte, 52, was killed in a collision involving four buses....
