The Satya Niketan PG building, which collapsed near Delhi University's South Campus on Monday killing seven people, had a chronic water seepage problem in its basement, police sources said.
Police are now searching for the labour contractor who was undertaking repair work in the basement for seepage. They are examining the circumstances under which the work was being carried out, and whether it contributed to any structural changes or violations that led to the collapse, they said.
MCD steps up enforcement in South Zone
The Municipal Corporation of Delhi has also stepped up enforcement in the South Zone. Official records dated September 7 show that the building department issued show-cause notices to five residential properties in Ward 160, covering areas including Maidangarhi, Saidulajab and Neb Sarai, while demolition action was recorded against another residential property in Saidulajab.
The decades-old Satya Niketan building, which housed a boys' paying guest accommodation, was spread over around 55 square metres and consisted of a basement and ground plus four floors. There were reportedly two rooms on each floor, with two beds in each room. The structure did not have columns and beams, police sources said.
The structure collapsed around 1.30 pm on Sunday while repair work was underway. A total of 12 people were pulled out of the debris, of whom seven were killed.
PG owners arrested in connection with collapse
Police have arrested the PG owners -- 81-year-old Hariram Gupta, a retired Indian Air Force sergeant, his 75-year-old wife Urmila Gupta, and their 52-year-old son Mahesh Gupta -- in connection with the collapse.
While Hariram was initially believed to be the property's owner, police said documents showed Urmila owned the building, while Hariram and Mahesh allegedly managed the PG.
The collapse also prompted action against civic officials, with MCD Deputy Commissioner of South Zone Rakesh Kumar and four engineers -- Superintending Engineer Ranvir Singh, Executive Engineer Lalit Kumar Goel, Assistant Engineer Sunil Chauhan and Junior Engineer Ashish Kumar -- suspended.
The MCD has ordered inspections of buildings across Delhi, particularly structures suspected of violating height and floor restrictions. Chief Minister Rekha Gupta has also directed officials to seal all five-storey structures in the city.
