"I strongly condemn this act. The BJP government at Centre is very vindictive. It is using the machinery for their own gains," Gogoi told a press conference here.
He pointed out that no action has been initiated against Chief Ministers of Madhya Pradesh and Rajasthan despite having serious charges.
"Shivraj Singh Chouhan and Vasundhara Raje have been involved in so many big scams. Why has no action been taken against them? It is a discriminatory attitude," Gogoi said.
The searches at Delhi, Shimla and others places started within minutes of the 81-year-old Singh leaving his official residence for Sankat Mochan temple here at 7:30 AM to solemnise the marriage of his daughter.
