The Delhi Police on Thursday raided several coaching institutes and so far questioned 35 people in connection with the leak of CBSE class 10 Mathematics and class 12 Economic papers.
"It has been established that both the papers were leaked before the scheduled dates of examinations and were circulated and exchanged on WhatsApp among some tutors and students. Among those questioned are 18 students, including seven college students, five tutors and two others," Special Commissioner of Police (Crime) RP Upadhyay said.
The top cop added that till now their investigation has not revealed that any money was charged in exchange for the leaked paper.
Upadhyay said that they are trying to establish the trail "which means finding the origin of the leakage, followed by how it was transmitted and who all were the beneficiaries".
"The Board has been cooperating in the probe. We have asked them things like how the paper is set, details of where the question papers are kept and how they are distributed to various examination centres. After we get these details, we will try to find out how the leak happened," the crime branch official said.
