The Central Bureau of Investigation on Tuesday denied allegations made by Arvind Kejriwal that the bureau raided his office and said that the raid was conducted at the office of the Delhi Chief Minister's principal secretary Rajendra Kumar.

According to reports, the CBI recovered foreign currency worth over Rs 3 Lakh from Kumar's residence. Besides, the bureau seized cash of Rs 13 lakh, including Rs 2.4 lakh from the residence of Kumar, during raids at 14 locations.

Documents pertaining to three immovable properties have also been recovered from Kumar's residence, IANS reported.

The CBI raided Kumar's office and residence on a complaint filed by former member-secretary of Delhi Dialogue Commission Ashish Joshi in July 2015. 

"In his complaint on 13 July 2015, Joshi had sought a probe into the dealings of Mr Kumar when he was associated with the departments of Education, IT and Health of the Delhi government," Firstpost quoted one of the officers investigating the allegations.

"Mr Joshi has alleged that Mr Kumar set up various companies when he was director of Education from May 2002 to February 2005 and later secretary IT and Health and Commissioner VAT. He awarded work orders of departments to these companies without floating tenders. This resulted in loss to the government's exchequer," the officer added.

Kumar is accused of setting up a company named Endeavors Systems and using his power after becoming secretary (IT) of the Delhi government in 2007 to get "the firm empanelled with public sector undertaking ICSIL, an IT PSU. The PSU status enables companies to do works of government departments without tenders", the officer said, Firstpost reported.

An FIR has been filed against Kumar, AK Duggal and GK Nanda, former MDs of Intelligent Communication System India Limited (ICSIL), RS Kaushik, MD of ICSIL, Sandeep Kumar and Dinesh K Gupta, Directors of Ms Endeavour Systems Private Limited under various sections of Prevention of Corruption Act and the IPC.

Even as the CBI claimed to have raided the office of Kumar, Kejriwal alleged that the agency went through the files in his office. The Delhi Chief Minister also blamed Prime Minister Narendra Modi for "political vendetta". He went ahead to call Modi a "coward" and "psychopath".

Denying claims that the Centre was involved in the raids, Union Minister M Venkaiah Naidu said, "CBI is an independent organisation... It has become fashionable for the Delhi chief minister to quarrel with the central government and take the PM's name for everything", IANS reported.
