The case was initially probed by Gujarat police, who arrested six persons, including Shiva Solanki, nephew of the BJP MP, and sharp-shooter Sailesh Pandya who is accused of shooting Jethwa outside the Gujarat High Court on July 20, 2010.
But police ruled out the possibility of Dinu Solanki's involvement.
Jethwa's father then approached the Gujarat High Court. The High Court termed the police probe as "far from fair, independent, bona fide or prompt", and transferred the case to CBI.
