Delhi Police has set up a special team to investigate the leak ofÂ two question papers of CBSE. The team began its probe starting with 25 people, mostly students who had been able to access the handwritten question papers.
A special investigation team led by senior police officer RP Upadhyay, who heads the crime branch, has been constituted after registering two cases on complaints from the CBSE.
Police are also tracking WhatsApp messages which appear to have been circulated in the recent days to trace the source.
"We have received snapshots of the handwritten paper circulated through WhatsApp from the complainant. We are trying to ascertain the source of these messages. Since WhatsApp messages are end-to-end encrypted, we are facing a bit of difficulty in tracing the source," said an officer privy to the probe, according to news agency Press Trust of India.
Any official from any of the examination centres or from the board are yet to be questioned, says the officer. The questioning will happen once the source of messages is traced.
CBSE cancelled two papers Class 10 mathematics and Class 12 Economics hours after the question paper surfaced on social media.
Union Education MinisterÂ Prakash JavadekarÂ later told reporters that "2-3 papers" had leaked but promised parents and students that the authorities had filed a police complaint right away. The minister underlined that the leaks appeared to be a localised problem limited just to Delhi.
Javadekar also said that the papers were leaked just half-an-hour before the examination. However, a police officer said that his understanding at the moment was that the papers appear to have been leaking an evening before the two examinations.
A police statement said the CBSE had registered the first case in connection with the leak of economics paper yesterday while the case pertaining to mathematics paper was filed today, following a complaint by the regional director of CBSE.
The cases were registered on charges of criminal breach of trust, cheating and criminal conspiracy.
The CBSE, however, denied any leak and urged students and parents not to panic.
â€˜â€™We have checked with all exam centres and the paper was not leaked. The source of circulation of this information is not known yet. We want to urge the students and parents to not panic and assure them that the board is doing its best to ensure sanctity of the examination," a senior CBSE official had said.
CBSE even received a fax on March 23 saying a person from Rajinder Nagar is behind the paper leak. As per the complaint, this person runs a coaching institute.
