Crime Branch, however, has been checking if the transport department destroyed the record following a periodic cleansing procedure.
Sources also reported that Crime Branch received some evidence against officials in connection with transport department. The officials allegedly had given clearance to Dinesh Yadav, the owner of the bus.
The bus did not have a fitness certificate and was impounded six times in two years. The deleted record could have helped widening the probe of the Crime Branch.
A 23-year-old paramedical student was gang-raped in the moving bus in the national capital. All six accused including a minor were arrested. In a shocking twist, one of the main accused Ram Singh was found dead inside Tihar jail. It is said to be a case of suicide.
The victim was brutally raped allegedly by all six men. The fast track court, where trial of the case has been going, recorded doctors' statements recently.
It was said that the victim was injured with weapons (rods). Recording the statement, doctor said, "Looking at the nature of the injuries suffered by the victim in her private parts, in my opinion, can be caused by the weapons produced before the court.
Initially the victim was admitted to Safdarjung Hospital in Delhi. Later she was taken to a hospital in Singapore where she passed away.
