Kejriwal blamed Prime Minister Narendra Modi government for victimising Yogendra Yadav's family "through the use of agencies like I-T".
On Twitter, he further wrote "Modi government should stop such vendetta politics," Kejriwal wrote on Twitter.
The Income Tax Department (ITD) on Thursday claimed that it has seized about Rs 27 lakh cash and a number of documents and payment receipts after it raided multiple premises of a hospital group in Haryana's Rewari, related to family of Swaraj India chief Yogendra Yadav.
A senior ITD official said that the department also recovered transaction receipts of about Rs 15 crore, suspected to be unaccounted, after the raids on the offices of the hospital group. The raids have ended now.
Department officials in Chandigarh also claimed to have found alleged documents related to the purchase of a land plot by the owners of the hospital group in the past, using a purported cash amount of Rs 93 lakh. This transaction is under investigation now.
About Rs 29 lakh cash was found as part of the raids that were launched yesterday morning. Out of this, about Rs 27 lakh has been seized on the suspicion of being alleged unaccounted money, the senior official said.
The officials added that they have got "vital leads" on the purchase of a diamond jewellery by Yogendra Yadav's nephew Gautam Yadav, main partner in the hospital group. They had alleged that Gautam paid Rs 3.25 lakh in cash, out of the total Rs 6.50 lakh, for purchase of the jewellery from the diamantaire Nirav Modi's firm.
While Gautam climes that while purchasing the lone diamond ring from the Nirav Modi group about two years back he had "given his PAN number and it was a genuine transaction.".
Yogendra Yadav alleged that the Narendra Modi-led government was "targeting" his family through the raid.
The Swaraj India chief added that he would refrain from commenting further as this case is "now between the assessee and the tax authorities."
