The Delhi Police Crime Branch have arrested three people in Himachal Pradesh for allegedly leaking the Central Board of Secondary Education’s Class 12 economics paper last month, PTI reported on Saturday.

An unidentified police official identified the accused as examination centre superintendent Rakesh, clerk Amit and peon Ashok. The accused were arrested at the Dayanand Anglo-Vedic school in Himachal Pradesh’s Una district and have been taken to New Delhi.

Photos of a handwritten copy of the examination were leaked via WhatsApp. The central government has faced massive backlash after the question papers of the Class 10 mathematics and Class 12 economics test were leaked. The economics exam, originally held on March 26, will be conducted again on April 25, but the board decided not to re-conduct the Class 10 mathematics paper after it found the leak had little impact on the results.

The CBSE chairperson had been informed of one of the leaks via email, but said the examinations could not be cancelled without verifying the information received.

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 earlier in the day for allegedly being involved in the leak of the economics paper. On March 31, the Jharkhand Police had apprehended 12 people, including students and private tutors, in connection with the mathematics paper leaks.
