NEW DELHI, Nov. 16 (UPI) -- A multistory building in New Delhi that housed migrant workers collapsed Monday night, killing at least 64 people, authorities said.
Another 80 people were injured and a senior police official told the Press Trust of India it was feared more people were buried under the debris.
The 15-year-old building collapsed about 8:15 p.m. in New Delhi's Lalita Park area. City spokesman Deep Mathur and Chief Minister of New Delhi Sheila Dikshitt said the five-story building apparently fell because its foundations had weakened after exposure to water from this year's heavy monsoons, CNN reported.
"I believe it's an unauthorized building," Dikshitt said. "I believe there was water in the bottom of the basement for many days."
Illegal construction of a fifth floor was under way at the time of the collapse, PTI said.
Police have filed charges against Amrit Singh, the owner of the building. Singh and his family left the area shortly after the building collapsed, PTI reported.
