The Enforcement Directorate (ED) tweeted on Saturday that it had "attached" properties worth Rs 1,411 crore ($210.78 million) in the case involving a loan from state-owned IDBI Bank to Kingfisher to buy properties abroad.
The assets were purchased several years before Kingfisher was launched, Mallya said in a statement to the media on Sunday.
"There is no rationale nor any legal basis for the series of actions initiated by the ED which is now making it more difficult to raise resources to pay the banks," Mr Mallya said.
The ED says Mallya's United Breweries Group used Rs 430 crore of Kingfisher bank loans to buy property overseas.
Mallya's statement said Kingfisher had provided evidence that the funds were used for legitimate business purposes.
Creditors, led by State Bank of India, have rejected an offer of partial repayment by Mallya, who had given a personal guarantee for the Kingfisher loan. They want the former billionaire, who is living in Britain, to attend a hearing in India's Supreme Court.
The foreign ministry in April revoked a diplomatic passport that he carried as a member of parliament's upper house. A judge in Mumbai has non-bailable warrant for his arrest.
