Income Tax officials searched the three residences of Chandrashekar Swami, a popular astrologer here, on suspicion of tax evasion.
The search began on Saturday evening and is expected to continue well into the night, a source said.
It is suspected that evasion could be of at least Rs. 50 lakh.
The astrologer is popular with dignitaries such as Srikantadatta Narasimharaja Wadiyar and Bollywood actors, including Amitabh Bachchan, who consulted him for the marriage of his son Abhishek with Aishwarya Rai.
