New Delhi authorities searched for the owner of a building that collapsed and killed 66 people, the Press Trust of India reported, as the city's administration blamed unauthorized construction for the accident.
Local channels aired images of rescue workers pulling bodies and the injured out of the rubble of the four-story building that housed migrant workers and their families in the eastern part of New Delhi. About 130 people were wounded and at least 10 are still trapped under the debris, PTI reported.
"We will punish acts of negligence and officials responsible for this," New Delhi Chief Minister Sheila Dikshit told reporters earlier in televised comments at the site, after ordering an inquiry.
The city's police have registered a case of culpable homicide not amounting to murder against the missing owner, the PTI said, citing a law enforcement official it didn't name.
Recent monsoon rains and flooding from the neighboring Yamuna river may have resulted in seepage and weakened the building's foundation, PTI said.
