MUMBAI — Continuing its probe into the Adarsh housing society scam, the Central Bureau of Investigation (CBI) on Tuesday raided the homes of Jairaj Phatak, the former municipal commissioner of Mumbai, across three cities in the country. Phatak, an Indian Administrative Service officer — and now additional secretary at the rural electrification department at the centre – is accused of having approved the height of the controversial building by 10 metres. In return, his son was given an apartment in the building.
