Government is seriously examining the issue of a high-rise Apartment constructed in the naval area in Mumbai in alleged violation of rules. Defence Minister A K Antony told this to reporters after coast guard commanders conference in New Delhi on Monday. The Navy has objected to Maharashtra government's permission for Occupation Certificate to 31-storey Adarsh Society building in Colaba, citing serious security concerns. Navy sources said, the 100-metre tall building next to a planned helipad and military installations has violated the limit of a height of 30 metres.
