Bihar Deputy Chief Minister Tejashwi Yadav has been summoned by the Central Bureau of India for questioning in the land-for-jobs scam on Saturday. Yadav, the younger son of former Minister of Railways Lalu Prasad Yadav, was earlier summoned by the CBI on March 4 but he had not appeared before the probe agency. The CBI has summoned the Rashtriya Janata Dal (RJD) leader based on evidence and a paper trail against him.
