The action comes at a time when the city is reeling under the worst attack of dengue in last six years which has affected around 6,500 people as hospitals continued to be flooded with patients affected by the mosquito-borne fever in which 37 people have died so far.
The action against Sanskriti School in Chanakyapuri area comes two days after a 16-year-old student of the school had died due to medical complications caused by dengue.
The civic body has issued yet another notice to the director of All India Institute of Medical Sciences (AIIMS) to clear the aedes mosquito breeding spots from its campus at the earliest failing which the NDMC will remove them and impose a fine on the institute.
"Despite being challaned nine times and 17 notices being served by NDMC, the institute has failed to take preventive measures to check breeding of mosquitoes. We had sent a notice to the AIIMS Director two weeks back for violating provisions of the NDMC Act. However, no action has been taken yet by them so another notice has been issued," the official said.
"We have issued a total of 248 challans this season for mosquito breeding inside institutions and households and served 3,600 notices.
"During the inspection, if the premises are tested positive for mosquito breeding, they are issued notices. But if no improvement is found in the hygiene conditions during the next inspection, the defaulters are issued challans," the official said.
