Court has granted CBI four-day custody of all the four accused in the Railway bribery case. In the same case, Bansal has defended himself against the charges. In a press statement issued by him he has said, "I have to say that I had no knowledge or clue about the matter at all. Though a close relative, he or any other relative of mine does not and cannot meddle in my official functions or influence my decisions. There is also no business relationship between his and my family. I look forward to an expeditious investigation by CBI in the matter".
