MUMBAI: Stuck under concrete and dust, Ahmed Ali (21) held on to his cellphone like it was his last straw of hope. He gathered every bit of energy to dial 100, the police emergency helpline, and told the operator that he was in need of urgent help as a building had collapsed on him.“I was talking on phone when the building came crashing, so I could immediately dial 100. The person on the line asked me if I could explain the address clearly. I repeated that the area was Bhendi Bazar but the police person asked me to provide a detailed address. By then the line got disconnected,” he told TOI, lying in a cot in ward 18 of JJ Hospital with fracture in both lower limbs.“I tried calling a second time but couldn’t get through. By then, I got a call from the helpline and I was again asked to explain the address. The line got disconnected again,” he said. He was eventually rescued by fire brigade officials. “I am just happy to be alive,” he said.A native of UP, Ali had recently got married. He works in a general stores nearby and used to sleep on the ground of the Hussaini building.
