Port Blair, March 4: The Port Blair Municipal Council has sealed a building/structure on Survey no. 2686/P situated at village Aberdeen, Ward no. 14 without obtaining any approval of building plan. The said building is being constructed illegally without obtaining any prior approval from the Council and is in gross violation of the Building Bye laws. Despite serving demolition notice, the building owner failed to comply with the directions of the PBMC and did not demolish the unauthorized building and continued the construction work unabated thus compelling the PBMC to seal the building.
