Two private school teachers and a tuition teacher have been arrested on Sunday for their alleged role in leaking the question paper of the CBSE examinations. With these arrests, the trail has been traced back to source, the police said.

Deputy Commissioner of Police (Crime Branch) Dr. Ram Gopal Naik confirmed that the three — Rohit, Rishabh and Tauqeer — were arrested in the early hours of Sunday from Bawana. Sources said that Mr. Rohit and Mr. Rishabh are teachers in a private school and Mr. Tauqeer runs a coaching centre.

"Rohit is a Physics teacher and Rishabh is a Mathematics teacher. They both had access to rooms where the question papers were kept before the exam. They used to click pictures of the questions and send it to Tauqeer who would further share the questions with his students after writing them down on a different paper," said a senior police officer.

The police said that they're questioning other staffers of the school and the coaching centre.
