The Central Bureau of Investigation (CBI) on Thursday raided the official and residential premises of Manoj Kumar Agrawal, a top Delhi Development Authority (DDA) official.
The agency also lodged a case against Agrawal for owning assets disproportionate to his known sources of income.
CBI's teams of investigators raided eight official/residential premises of Agrawal, including four in Delhi, two in Ghaziabad and two in Mathura.
Agrawal, an Indian Administrative Service (IAS) officer, was personal secretary to former information and broadcasting (I & B) minister Priya Ranjan Das Munshi in his earlier stint.
The agency's investigators have till now recovered movable and immovable assets worth several crore of rupees, including Rs 2.75 lakh in cash, Rs 50 lakh as fixed deposits in multiple bank accounts, and ownership documents (in his name/family members' names) of eight plots, according to CBI's spokesperson Harsh Bhal.
The CBI, said an investigator who requested anonymity, suspects Agrawal allegedly "amassed his disproportionate assets during his stint in the I&B ministry by cutting deals with media organisations."
Agrawal had assisted Munshi during his stint as central water resources minister.
Even as a CBI team begun its raid at Agrawal's posh flat S 72, at Nivedita Kunj in RK Puram, it allegedly found a "packet containing Rs 2.75 lakh", said the investigator. "Somebody, he or his family member, thrown out the packet hoping we would not get hold of it," he said.
Agrawal, a 1990 batch IAS officer of West Bengal cadre, was currently Commissioner, land disposal in DDA and joined the department a month ago.
The CBI has found evidence that he owns "five bank lockers -- located in Delhi -- that are expected to contain cash and other valuables worth crores," said the investigator.
In a related move, the CBI raided the residential premises of a chartered accountant based in Ghaziabad. The man was allegedly involved in the illegal deals done by Agrawal.
CBI has found documentary evidence of Agrawal owning plots in Dwarka, Gurgaon, Greater Noida and Ghaziabad.
The agency has recovered documents pertaining to his investments in the Brijwasi Education & Welfare Society and other stocks and shares.
