CBSE paper leak: 'It happened either in board's custody or at the banks'

The probe into the leak of CBSE class 10 maths and class 12 economics question papers has led the police to believe that the leak happened between the time the papers were in custody of board officials and when those were kept in banks, a senior official said.

With the arrest of three men, including two teachers of a private school in Bawana, police claimed to have busted a module in which the teachers had shared WhatsApp images of the economics paper one-and-a-half hours prior to the exam.

However, when it comes to the trail of handwritten papers that were circulated a day or two before the exam, police are sure that the leak happened either at the board level or the time when they are kept in the banks, the police officer privy to the probe said.

Since it is suspected that the leak might have happened from outer Delhi or Haryana, police have started scanning CCTV footages from the banks in certain areas to see whether there was some suspicious activity around the time the papers were kept there.

The police are also probing the roles of CBSE officials. So far, no CBSE official has been questioned so far, the police officer said.
