An entire lane was evacuated after residents of southwest Delhi's Mahaveer Enclave noticed the top-floor of an under construction building tilting dangerously on Saturday morning.
"We received a call at 11:45 am from a resident of the area who claimed that a building in the locality was about to collapse. We forwarded the complaint to the civic agency concerned and dispatched local police to the spot," said R S Krishnia, additional commissioner of police (southwest).
Police said the residents were concerned with a five-storey building which had been built on a small 27 square metre plot.
"It looked as if the entire fourth floor of the building was about to fall down and would subsequently bring down the whole building. Our area has a lot of unauthorised buildings and we don't want to suffer the same fate, so we decided to contact the police," said Vijay Sharma, a local shopkeeper.
Police said some MCD officials accompanied by a team of the local police rushed to the area soon after the phone call.
"We cordoned-off the area when the civic agency officials decided that they would serve a notice on the builder responsible for the construction and that the fourth floor had to be demolished," said a senior Delhi Police officer who was leading the police party accompanying the civic agency officials.
"The MCD brought its team at 4 pm and the demolition of the fourth floor was undertaken. The entire area had been cordoned-off keeping the safety of residents in mind."
