Mumbai, Jan 29 (Agencies): Former Maharashtra Chief Minister Ashok Chavan has been named among 13 in the FIR filed by the CBI in Adarsh society scam. The agency also listed former Major General MM Wanchoo, RC Thakur and Kaniah Lal Gidwani as main conspirators in scam.

After the Bombay High Court pulled up the CBI for laxity in probing the Adarsh housing society scam, CBI registered a case against some retired Army officials and bureaucrats of Maharashtra government on Saturday.

The agency had registered an initial enquiry into the scam in November last year.

The decision to register a case was taken after seeking a legal advice on the proof which convinced registering of a case against some people for allegedly forging documents and misusing official position.

Lat week, while hearing a petition in the case, a division bench of Justices B H Marlapalle and U D Salvi had questioned CBI why it had not registered the case.

"It has been more than two months since CBI has been conducting a preliminary inquiry into the case. Why have you (CBI) not registered FIR as yet?," it had asked.

Two former Army Chiefs Gen Deepak Kapoor and Gen N C Vij and ex-Navy Chief Admiral Madhavendra Singh owned flats in the scam-hit society building in upscale area of Colaba. However, the former top chiefs have claimed that they have now surrendered the flats and that they were unaware the property was only meant for Kargil martyrs’ kin.

The Union Ministry of Environment and Forests had on January 16 ordered demolition of the building within three months, holding it as "unauthorised" and built in violation of the spirit of coastal regulations.

Apart from violating the CRZ norms, the society is alleged to have got clearances from various authorities through dubious means.
