Waking up to the threat posed by unauthorised constructions after the tragedy in Laxmi Nagar, the municipal corporation of Delhi (MCD) has asked the occupants of as many as 38 "dangerous" buildings in east Delhi area to evacuate immediately.

"During a survey, basements of at least 38 buildings were found to be water-filled. We have issued them notice to vacate their houses immediately for their safety," MCD spokesperson Deep Mathur said.

The preventive action has come in the wake of Monday night building collapse that claimed 67 lives and left 73 injured in the area. The basement of the four-storey building was waterlogged for the last two months due to the heavy rains, according to the government authorities.

Over 60 families were living in the cramped quarters of the 15-year-old building, where an illegal fifth floor was under construction.

The survey is being undertaken within a radius of 300 metres from Pushta Road where the building collapsed.

Yamuna river had flooded the area during the monsoon and Mathur said that more buildings will be vacated in case they are found unfit for inhabitation.

Following the incident the Delhi government has constituted one man commission to enquire into the building collapse mishap. A former High Court Judge, Justice Lokeshwar Prashad will conduct the enquiry and will submit the report within 90 days.
