RJD leader Lalu Prasad's family is once again in the news for a wrong reason. It's at the centre of a row over allegations that the Sanjay Gandhi Biological Park or Patna zoo, which is under the charge of his minister-son Tej Pratap Yadav, awarded a Rs 90-lakh contract for earth-filling work and construction of pathways to a company that ferried soil from a proposed mall site owned by a firm in which the minister, his siblings and mother are shareholders. Under fire from the Opposition BJP, Lalu Prasad said, "We are ready for any kind of investigation. We offer free dung to Patna zoo." Mrityunjay Tiwari, RJD spokesperson, said Deputy Chief Minister Tejashwi Prasad Yadav had clarified that the contract was worth Rs 44 lakh and not Rs 90 lakh. Tiwari said it was awarded for "soil purchase" and that all norms had been "duly complied with". Asked for his comments on allegations that the contract was awarded without floating a tender and that soil was transported to the zoo in trucks at night, JD(U) spokesperson Neeraj Kumar said: "We believe that the Patna zoo authority should have followed contract norms and should have ensured that animals were not disturbed by the movement of trucks at night."
