Emergency teams including the Delhi Fire Service, police and disaster-response personnel were deployed to the site to search through the debris.The building's collapse has raised serious questions about unauthorised construction and enforcement of building regulations in the densely populated student neighbourhood.A senior MCD official said the structure itself was illegal. Reports indicate that the building stood on a small plot and had a basement and four floors, despite local norms allowing substantially less construction in the area.MCD Orders Sealing of Illegal BuildingsIn response to the tragedy, the MCD has directed that all illegal constructions exceeding four floors be sealed immediately.Mayor Pravesh Wahi said the authorities would not spare those responsible for the Satya Niketan incident. He also warned that officials found guilty of allowing such structures to be built would face severe consequences, including immediate dismissal.The order expands the response beyond the collapsed PG and signals a wider inspection and enforcement drive against unauthorised multi-storey buildings in Delhi.Delhi CM Rekha Gupta Orders InquiryDelhi Chief Minister Rekha Gupta has ordered a magisterial inquiry into the collapse and directed authorities to identify those responsible.An FIR has also been registered against the alleged owner of the building. The government has said that anyone found responsible for the incident will face action under the law.The inquiry is expected to examine the building's construction history, permissions, structural condition and the repair work reportedly being carried out before the collapse.What Went Wrong at the Building?Initial reports have pointed to several possible safety and regulatory violations. These include unauthorised additional floors, repair work in the basement and structural weaknesses.Reports also indicate that the building did not have a sanctioned building plan and lacked a fire safety clearance. Authorities are investigating whether unauthorised construction and repair work contributed to the collapse.A separate report has also highlighted concerns about a waterlogged basement and the absence of adequate structural support. However, the exact cause of the collapse will be established through the ongoing investigation.Student Safety Concerns Rise in DelhiThe tragedy has sparked renewed concerns over the safety of PGs and hostels in Delhi, particularly in areas heavily populated by students.Student activists protested outside the MCD headquarters, alleging negligence in enforcing safety regulations at paying guest accommodations. They demanded stronger inspections and immediate action against unsafe buildings.Satya Niketan and nearby areas are popular among students because of their proximity to educational institutions. The collapse has therefore raised wider questions about whether older residential properties are being converted into high-occupancy PGs without adequate structural and fire-safety checks.Delhi Building Collapse: Rescue OperationsRescue teams worked through the debris after the building came down on Sunday. The National Disaster Response Force, Delhi Fire Service, Delhi Police and other agencies participated in the operation.Several people were rescued from the collapsed structure, while others were feared trapped during the initial stages of the operation.
