KS Rana, an official in-charge of the CBSE exam centre in outer Delhi's Bawana was suspended and three men were arrested on Sunday over the leak of Class 12 board exam papers, Union education secretary Anil Swarup tweeted.
Besides Rana, three persons, including two teachers of a private school at Bawana in outer Delhi, were arrested by the Crime Branch.
The accused have been identified as Rishabh, 29 and Rohit, 26, both teachers at a private school in Bawana, and Tauqeer, 26, a tutor at a private coaching centre there, they said.
On the days of the examination, Tauqeer used to circulate leaked question papers about an hour before their beginning among his tuition students who would further circulate them among their friends. He used to get the leaked papers on WhatsApp from Rishabh, who is a Physics teacher and Rohit, who is a Mathematics teacher, at the same school.
Joint Commissioner of Police (Crime) Alok Kumar said, "It is at 9.45 am when the papers are opened. The teachers' duo used to click the pictures of the papers 40 minutes prior to that and send to Tauqeer who further used to circulate to the students."
Rohit used to send the papers to Tauqeer on Rishabh's instructions.
The police zeroed in on Tauqeer by following four WhatsApp numbers provided by the CBSE in its complaint and used for circulating the leaked papers, another officer said.
A student who had got the paper was found and he led the police to Tauqeer who was detained yesterday. He shared details of his accomplices with the police after which the trio was arrested, the police said.
The trio is currently in police custody for two days during which they would be questioned over the money trail and whether they have leaked other papers.
Another teacher at a private school is also under the scanner for his alleged role in the leakage of papers and the police are on the lookout for him.
The Delhi Police had registered two cases involving the leaks.
The first case, related to the leak of Economics paper was lodged on March 27, while the other pertaining to the leak of Mathematics paper was lodged on March 28, following a complaint by the CBSE's regional director.
The examinations for the Class 10 Mathematics and Class 12 Economic papers had been held on March 28 and March 26 respectively.
The Crime Branch has questioned over 60 people in connection with the CBSE paper leak case, including the administrators of over 10 WhatsApp groups on which the leaked question papers were shared.
Those questioned, including tutors and students, had revealed that they got the papers from someone else, an official privy to the probe said.
There is nothing till now to indicate that money was charged for sharing these papers, he said.
