A day after the much-touted survey of castes in Bihar hit a roadblock, RJD president Lalu Prasad on Friday let off a barrage of attacks at the opposition BJP in the state. Taking to Twitter, the septuagenarian made no reference to the Patna High Court order staying the survey, but accused the saffron party of being "afraid" of a headcount of 'bahusankhyak' (majority) backward classes.
