The wall of a dilapidated chest clinic run by the Municipal Corporation of Delhi (MCD) in Lajpat Nagar of south Delhi collapsed early on Saturday.
While no one was seriously injured, six labourers sleeping near the construction site sustained minor injuries, police said.
The building had been declared “dangerous” by the MCD a year ago. There were no people inside when the incident was reported.
The collapse took place around 2 am in Nehru Nagar area of Lajpat Nagar. The police said none of the labourers were taken to hospital as the injuries were minor.
The police said they received a call about the incident only around 9.30 am on Saturday.
“We were informed by the fire officials about the incident. The rubble was cleared and no one was found under it. We counted all the labourers at the construction and no one was found to be missing,” said a senior police officer on condition of anonymity as he is not authorised to speak to the media.
The MCD said demolition work was underway.
The MCD engineer chief has asked the chief engineer to submit an enquiry report in the matter.
According to Deep Mathur, director, press and information, MCD, “The building was being demolished by the contractor to carry out repair work. It seems the mishap took place during that time but we are yet to ascertain the reason behind it.”
The enquiry report would be submitted within a week, he added.
Police said since they have not received any formal complaint they would not register any case.
