Official sources said the searches were conducted on at least three separate Muthoot groups companies in Kerala's Thiruvananthapuram, Kochi and Kolencherry and cities like Delhi, Mumbai, Coimbatore, Chennai and Bangalore.
An official, who is not authorised to speak to the media, confirmed that the action was being conducted on three separate Muthoot financial organisations.
They said the department had some "actionable intelligence" on the financial activities of the group and hence the searches were carried out. "Documents and computer peripherals have been seized from various premises," they said.
The searches that began early morning are still underway, they said.
