New Delhi: The Delhi Police are suspecting that the CBSE question papers might have been leaked from neighbouring Haryana, a senior official privy to the probe said on Monday.
The police were investigating whether some schools in Sonepat, Jhajjar and Bahadurgarh were also involved in the leak of Class X Mathematics paper and Class XII Economics paper of the Central Board of Secondary Education (CBSE), he said.
"We are probing that angle. It is suspected that some schools and even some CBSE official might be involved in the matter. But we cannot say anything with surety at the moment," the official said.
"The papers were mostly circulated in outer Delhi and areas bordering Haryana. This indicated that the origin of the leak might be in Haryana or there was some collusion from there," he said.
Three persons, including two teachers of a private school at Bawana in outer Delhi, were arrested by the Delhi Police Crime Branch for their suspected roles in leakage of the Class XII Economics paper.
The arrested persons were identified as Rishabh (29) and Rohit (26) both teachers at the private school, and Tauqeer (26), a tutor at a private coaching centre.
The Delhi Police has lodged two cases over the leaks of the CBSE question papers.
The first case related to the leak of economics question paper was lodged on March 27, while the other pertaining to the leak of Mathematics paper was lodged on 28 March, following a complaint by the CBSE's regional director.
The examinations for the Class X Mathematics and Class XII Economics papers were held on 28 March and 26 March respectively.
