"When he was a minor and didn't even have mustaches, he owned 13 properties. And after he was an adult, he became the owner of 13 more properties," Modi said.
Modi, who is the state BJP Parliamentary Party chief, said there's a difference between a general FIR and a CBI FIR as the investigation agency files FIR after it finds evidences of irregularities.
Lalu Prasad, his wife and former Chief Minister Rabri Devi and their son Tejashwi Yadav have been named accused in a CBI case related to the transfer of three acres of prime land in Patna to the family by two businessmen allegedly in return for licences granted to run IRCTC hotels in Ranchi and Puri when the RJD chief was the Railway Minister.
While Tejaswi had stuck to his gun not to quit, BJP leader Sushil Kumar Modi reiterated his demand asking for Tejashwi's resignation.
Both Tejashwi and RJD President Lalu Prasad Yadav have ruled out resignation for the Deputy Chief Minister, who is embroiled in corruption charges.
Tejashwi has maintained that all is well as long as the alliance with JDU is concerned.
Amid the present acrimony between ruling JDU and RJD of the grand alliance, BJP said it does not favour snap polls in Bihar.
The party also extended support to Nitish Kumar's stand that deputy chief minister Tejashwi Prasad Yadav must come clean on corruption charges against him.
BJP sought to steer clear of the acrimony between the two ruling allies saying it is not going to extend inside or outside support if JD(U) severs ties with RJD.
