He alleged the funds obtained from foreign agencies were used to trigger civil society movement in the country.
He also asked Kejriwal to disclose details of the donations received by his NGO Public Cause Research Foundation in the last fiscal.
"If Kejriwal has been exposing everyone's corruption, he should also answer the doubts regarding fundings to his NGO. I am following Kejriwal's way to expose him through media and later I will go for legal proceedings against him," Arora said.
Rejecting the allegations, an IAC spokesperson said all money received by Kabir were accounted for.
"Kabir had received grants from Ford Foundation in 2005 and 2008. Ford Foundation had agreed to pay USD 2 lakh in 2010 but the NGO wrote to it saying they did not need the money as it was into the anti-corruption movement," the spokesperson said.
The IAC also said the Home Ministry had conducted searches and inquired into the accounts early this year and had found nothing.
