The Central Bureau of Investigation (CBI) recovered 31 gold biscuits and 800 grams of silver from the bank locker of Sanjay Pratap Singh, a senior bureaucrat in the Delhi government, who was arrested in a bribery case on Wednesday.
Mr Singh has five bank lockers including a joint one with his wife, the CBI sources said.
The CBI officers also found 300 bottles of liquor brands like Blue Label, Glenmorangie and expensive watches like Rolex, Rado and various other labels.
The CBI sources said that so far, documents related to eight properties in areas including Safdarjung Enclave in Delhi, Sector 56 in Gurgaon, Sector 44 and Sector 50 in Noida and high-end construction in Greater Noida which is worth around Rs 20 crore, have also been recovered by the agency.
The fixed deposit receipts of over Rs one crore were also found during search operations conducted on Tuesday.
Earlier during the day, Delhi's Deputy Chief Minister Manish Sisodia said the government had been keeping an eye for long on the arrested bureaucrat, but there was no evidence against him.
"We had heard about SP Singh. But no solid information was coming our way. We were keeping an eye on him," Mr Sisodia said.
The 1984 batch Indian Administrative Service officer is the Principal Secretary of the Department of Welfare of Scheduled Caste, Scheduled Tribes and Minorities in the Delhi government.
The CBI said that Mr Singh had allegedly demanded Rs 2.2 lakh from the complainant whose firm provided security guards and subordinate staff to the department.
The private assistant of the senior bureaucrat has also been detained.
