The Municipal Corporation of Delhi (MCD) has launched an investigation into potential building bylaw violations following a tragic fire in Vivek Vihar that claimed nine lives on Sunday morning. Mayor Parwesh Wahi stated that action will be taken against officials if irregularities are found in the building's approval process. Preliminary investigations suggest the fire, which broke out around 3:30 AM, was likely caused by an air conditioning unit explosion or short circuit, rapidly spreading to upper floors. A joint team from the fire department and the electricity inspector will inspect the site and submit a report to the police. Concerns have been raised regarding the building's compliance with safety norms, including the number of dwelling units exceeding legal limits and inadequate staircase design. The mayor has appealed to residents to ensure fire safety measures are in place, emphasizing the importance of accessible escape routes during emergencies.
