Appearing before Special Judge Narottam Kaushal, ACP Crime Branch Suresh Kaushik said, "The enquiry into the matter is pending for want of information from Transport Department.
"Reply is still awaited in response to the notice issued to officials of the Transport Department for providing names and details of officials posted at the relevant time (when the bus in which gang-rape was committed was given licence illegally)," he told the court.
The court granted time till May 18 to file a report on its enquiry while expressing disappointment for such delay.
The case pertains to a complaint filed by RTI activist Vivek Garg seeking directions to the Crime Branch of the Delhi Police to register an FIR against the Transport Minister, the Transport Commissioner and others for allegedly committing offences of corruption, cheating, criminal breach of trust and criminal conspiracy.
