CBI raids were conducted at the BJP leader's residence at Shimoga, Dollars' Colony in Bangalore and Bellary.
"This is a normal CBI inquiry that is going on. BJP has to face embarrassment. In Karnataka, there are so many problems. BJP is power hungry. They are not worried about the people, they are only fighting for power," said RV Deshpande, President of Former Karnataka Pradesh Congress Committee (KPCC).
"The Supreme Court has ordered a specific probe against Yeddyurappa. It is about the funding received by an NGO run by Yeddyurappa's family. The NGO was funded by mining and industrial companies," said a CBI official.
The raids were conducted following an FIR lodged on May 15 against the former CM, his 2 sons and 2 others in the illegal mining case.
Reports reveal that important documents have been seized from Yeddyurappa's residence.
Meanwhile, Yeddyurappa will seek an anticipatory bail in the case with the special CBI court.
