Tejashwi is younger son of RJD chief Lalu Prasad. He said Bihar Governor Satyapal Malik has written two letters to Nitish Kumar on the crime, asking him to take strict action against the culprits. "Indirectly the Governor has questioned Chief Minister's criminal silence...I will awake Nitish Kumar's inner voice and expose his fake morality," Tejashwi said.
