Cracking down on the accused in the Adarsh Housing Society scam, a senior IAS officer in the Maharashtra government and two former Major Generals of the Army were arrested by the CBI on Wednesday for their alleged role in the irregularities.

With the arrest, the number of people in CBI custody in connection with multi-crore rupee scam has gone up to seven.

The arrests came before today's hearing in the Bombay High Court which has pulled up the investigating agency for its lackadaisical approach in the case.

Vyas, a 1989-batch IAS officer from Maharashtra cadre, was arrested here from his residence after the CBI received a sanction from Department of Personnel.

48-year-old Vyas is at present working as Secretary, Expenditure Department of Finance in Maharashtra government.

According to the CBI case, Vyas, during his tenure as collector from August 2002 to May 2005, allegedly connived with the other accused persons of Adarsh society and accepted false documents as proof of income and granted membership to those persons who were not eligible.

Vyas?s wife Seema Vyas was allotted a flat in return for the favour, the CBI has alleged in its FIR.

Ahead of Vyas's arrest, the CBI nabbed two Major Generals -- A R Kumar and T K Kaul. While Kumar was arrested from Hyderabad and was being brought to Mumbai on a transit remand, Kaul was called from Nashik and placed under arrest.

Kumar and Kaul are alleged by the agency of misusing their official position and fraudulently and illegally issuing No Objection Certificates (NOC) to the collector of Mumbai for development of the land. .
