MUMBAI, June 9 -- "I don't know how I will face his parents," said Rorojale Ahmed, 34, as he placed the body of his nephew into an ambulance at LTMG Hospital, Sion. Ahmed is the uncle of Niyaz Ahmed, 26, the delivery worker killed in the BEST bus accident at Dadar on Monday. "He was interested in nothing but work," said Ahmed, struggling to hold back tears. "He never spent on himself. Everything he earned was for his parents and to help get his younger sister get married." Niyaz had moved to Mumbai from Uttar Pradesh in search of work, shortly after finishing school, six years ago. Like countless young migrants drawn to Mumbai, Niyaz had just one goal - to support his family back home, said his neighbour Barkatullah Ahmed, 47. Rorojale Ahmed said the young man carried a heavy burden after his father, a labourer in Mumbai, began losing his eyesight. "Niyaz worked a series of jobs in Mumbai, starting with selling onions and potatoes, assisting tempo drivers, and eventually turning to gig work, which paid better," he said. In the trauma ward of the hospital lies 22-year-old Vrishabh Gupta, a second-year BCom student at Kirti College, battling critical head injuries. Gupta is a part-time Instamart delivery worker. As investigators piece together the sequence of events in the mishap, those inside the bus recalled the terrifying moments. Mahesh Doiphode, 50, a BEST inspector in the bus when it crashed, said, "Everything happened in a split second. We shouted at the driver to steer the bus to one side after it went out of control, to minimise the damage." The driver Vikas Dattaram Padave, 42, too is being treated for minor injuries. However, the other injured - a pedestrian Amit Mhatre, 41; BEST inspector Satish Waghmare, 48; and bus conductor Rajendra Pelekar, 57 - appear to have left the hospital soon after admission....
