At least six people have been killed and rescue operations are ongoing after a five-storey residential building collapsed in Satya Niketan, a densely populated neighbourhood in south-west Delhi close to Delhi University's South Campus, on Sunday afternoon. The building, known as Hostel Daze, came down around 13:30 local time, with eyewitnesses reporting that between two and four dozen people — mostly students — were inside at the time. The collapse, described by one nearby shopkeeper as sounding "like the rumble of an earthquake," sent clouds of dust and smoke through the narrow lanes of the neighbourhood.

By Monday morning, 12 people had been recovered from the rubble: six were confirmed dead, while the other six were receiving treatment at AIIMS hospital and reported to be in stable condition. Delhi Chief Minister Rekha Gupta, who visited the site on both days, said that approximately 80% of the debris had been cleared, with only the basement section remaining. Multiple agencies — including the Delhi Fire Service, the National Disaster Response Force, and the Delhi Disaster Management Authority — worked through the night on rescue efforts. An FIR, a formal criminal complaint under Indian law, has been registered against the building's owner, Hariram Bansal, who remains at large. A magisterial inquiry has also been ordered.

Authorities are investigating what caused the collapse. Gupta pointed to "accumulation of water, combined with ongoing repair work in the basement" as the likely trigger, while civic officials noted that heavy monsoon rains may have caused seepage that weakened the structure. Local residents and shop owners said the building — at least 50 years old — had been undergoing excavation work in its basement to expand its capacity. A neighbouring building has been evacuated as a precaution and ordered to be demolished.

The tragedy has thrown a harsh light on the chronic student housing crisis surrounding Delhi University's South Campus. Of the seven colleges in the area, only two provide hostel accommodation — offering a combined total of around 200 beds for thousands of outstation students. This has driven enormous demand for private paying guest (PG) accommodation in Satya Niketan, where many buildings have been converted from residential homes into cramped, commercially operated hostels, often without adhering to civic regulations. Students pay roughly 13,000–18,000 rupees (approximately $155–$215) per month. In the aftermath of the collapse, civic authorities began removing PG signboards across the neighbourhood as part of an enforcement sweep.

Building collapses are a persistent problem in Delhi, with fire department records showing more than a thousand incidents over the past three years, commonly attributed to poor foundations, substandard materials, and unregulated construction. Student groups and opposition politicians have called for a full safety audit of PG hostels across the city, and the National Students' Union of India demanded accountability for anyone found negligent. "Negligence with the safety of students and common people will not be tolerated at any cost," the organisation said in a statement.
