The Delhi Police Crime Branch has sent the the Central Board of Secondary Education a list of students who allegedly received the leaked Class 10 and Class 12 question papers ahead of the board exams, PTI reported on Monday, quoting unidentified police officials. The CBSE had reportedly requested the Delhi Police to share the details of the students who had received the leaked papers.

The police also reportedly told the CBSE that the principal of the school from where the paper is believed to have been leaked is not cooperating with the investigation. The principal was granted anticipatory bail and has since made himself unavailable for the investigation, a senior police official told Scroll.in.

The list of 60 students was sent to the board last week, PTI reported.

Question papers for the board’s Class 10 mathematics and Class 12 economics tests were leaked in March. While the Class 12 economics paper was conducted afresh, the board decided not to re-conduct the Class 10 exam after it found that the leak had had little impact on the results. Results for the Class 12 CBSE exams were declared on Sunday, and the Class 10 exams were out on Tuesday.

In April, the Delhi Police arrested three people from Himachal Pradesh’s Una district for allegedly leaking the Class 12 paper.

On April 1, a Central Board of Secondary Education official was suspended for alleged lax supervision of the Class 12 economics examination. The suspension followed the arrest of two teachers and the owner of a coaching centre in Delhi earlier in the day for allegedly being involved in the leak of the economics paper. On March 31, the Jharkhand Police had detained 12 people, including students and private tutors, in connection with the mathematics paper leaks.
