Worli - The slum-dwellers from Gopal Nagar, Hanuman Nagar, Udyog Nagar-1 and 2, Tilak Nagar had received 270 sq ft flats under the redevelopment project of the SRA. The concerned builder has constructed 23-storey high rises and the flats were handed over to the beneficiaries. Many of the beneficiaries had bagged 2-3 flats in these buildings. Taking benefit of their possession, many have allegedly sold their flats. The high court had asked the authorities to verify this fact. Accordingly, notices for survey were issued to the residents of these flats. The survey work was started in Gopal Nagar area on Monday but there was confusion as the actual possessors of these flats were asked to show their ID cards and other proofs. After the chaos, the survey was stopped and it was to be conducted in the presence of police. The residents are still clueless about the status of survey.
