The Mahul residents, who were allotted accommodation meant for project-affected persons (PAP) two years ago, are still refusing to move in to the flats owing to the 'toxic' air in the area. This has prompted the civic officials to re-allot more than 5,000 flats in the region.

BMC officials said that 5,137 of the 10,881 flats in Mahul were allotted to people from Tansa pipeline area and those living on footpaths or near nullahs about two years ago but they have refused to move in.
