MUMBAI, July 4 -- Panic gripped a seven-storey slum rehabilitation building in Andheri West on Friday afternoon after a massive fire erupted in the ground-floor meter room and raced through the building's electrical wiring, sending thick smoke billowing through stairwells and corridors and trapping dozens of residents inside. Around 50 residents, including children and senior citizens, were rescued by locals and fellow residents, who broke open window grilles to pull families to safety even before firefighters arrived. Residents said that this was the fourth fire-related incident in the building and claimed that repeated warnings about electrical problems had gone unaddressed. The fire broke out at around 2.15 pm at Building No. 1 of the Andheri United Cooperative Society in Andheri West. "I was offering Friday prayers when I heard people shouting that the building had caught fire," said 42-year-old Abdullah Shaikh, one of the first responders. "There was almost no visibility inside when we entered the building." Shaikh, along with other local residents, rushed inside and began rescuing those trapped before the Mumbai Fire Brigade reached the spot. "We had to break the window grilles and help people come out. Around 50 people were rescued. There were several senior citizens and children inside, and many were struggling to breathe because of the smoke," he said. Among those rescued was 44-year-old Asif Shaikh, who was trapped on the third floor with eight members of his family. They initially tried escaping through the staircase but were forced to retreat. "There was so much smoke that we could barely see anything. We started suffocating and had difficulty breathing," he said. "Even several hours later, I can still feel the smoke in my chest. We returned to our flat and began shouting for help. People from our locality broke the grills and rescued all eight of us. Otherwise, there were very slim chances of our survival."...
