Two teachers and the owner of a coaching centre were arrested by Special Investigation Team (SIT) of the Delhi Police Crime Branch on Sunday for allegedly being involved in the leak of the CBSE Class XII economics paper on Monday.
The police now believe that the leak originated from multiple sources and three were arrested from just one of the groups.
The three persons in Delhi were identified as Rishabh, Rohit and Tauqeer. They are teachers at a government schhol based in Outer Delhi. Tauqeer owns a coaching centre, the Delhi Police said.
A Delhi court remanded all three in police custody for two days. The arrests came just a day after the police caught 12 people in Jharkhand, in connection with Class X paper leaks.
The accused in Jharkhand had allegedly supplied the questions for money. However, the police could not trace the source.
The police are likely to question CBSE officials as they continue to investigate insider's role in the paper leaks.
On Saturday, the police received information from Google, with the details of email ids used to leak the papers.
After the leaks, the Central government faced huge fallout. The CBSE head had been alerted about the leaks via email, but stated that the examinations could not be cancelled without concrete evidence. Re-tests have been announced by the CBSE.
