CBI has filed four status reports in the High Court of Delhi in sealed cover regarding the investigation being carried out relating to the petitioners, the plea said.<br/><br/>Singh alleged that he was not allowed to see the closure report of the first inquiry and when the order was reserved by the high court, the status report filed by the CBI was perused by the court, the content of which is still unknown to him.<br/><br/>The chief minister said that there was no new information to initiate a fresh investigation against him and his wife and subjecting them to double investigation on same information is impermissible under law.
