Delhi chief minister Arvind Kejriwal's former principal secretary Rajendra Kumar and six others have been remanded to judicial custody till 27 July on grounds of corruption.
The CBI had arrested Kumar on 4 July; on 9 July, CBI had claimed that a forensic test of Kumar's voice samples suggested alleged corruption in awarding Delhi government contracts worth Rs 50 crore to a private firm.
The CBI also conducted searches at six premises in Delhi, Noida and Agra, including the offices of Kumar's chartered accountant (CA) in the national capital, during which they claimed to have recovered Rs 28 lakh in cash, an agency official said.
Kumar and four others were being probed by the CBI for allegedly granting undue favours to Endeavours System Pvt Ltd (ESPL) for getting the contracts.
The other accused are Tarun Sharma, deputy secretary in Kejriwal's office, Ashok Kumar, a former Delhi government employee considered as a close aide of Rajendra Kumar, besides owners of ESPL — Sandeep Kumar and Dinesh Gupta.
Kumar was allegedly sending voice messages instead of making phone calls to other accused and some unknown private persons to give details of bribes and modus operandi to commit the offence they all are involved in, the official added.
The CBI had cross-verified these voice samples with the audio tape carrying Kumar's voice during the ongoing investigation, the official claimed.
The agency had conducted a raid on Kumar’s office on 15 December, 2015, at the Delhi secretariat and seized documents and alleged that they prima facie reflected a criminal conspiracy and abuse of official position.
