New Delhi, April 01: Three persons including a coaching class owner were arrested by the Delhi Police’s Crime Branch Cell on Sunday in connection with the CBSE papers leak case. The arrests came after six teachers belonging to three different public schools and a school principal were taken in for questioning by the Crime Branch.

The principal and the two teachers who had been taken into custody late on Saturday were repeatedly quizzed following suspicion that they opened the class 12 Economics paper 75 minutes before the commencement of the exam in the presence of a few students on March 26.

Special Commissioner of Police R.P. Upadhyaya on Saturday said, “The SIT has so far questioned 53 students and 7 teachers in connection with the leak of class 10 maths and class 12 economics question papers. Six WhatsApp groups figuring in the trail of transmission of papers are also being looked into.” “Two more ACP-rank officers with their teams have been added in SIT for further probe,” he added.

The CBSE paper leak of class 10 maths and class 12 economics question papers has affected lakhs of students across India. Earlier the CBSE academic unit at Rouse Avenue near ITO had on March 26 received some sheets of handwritten answers of economics paper in an envelope without sender’s name.

The CBSE will conduct re-examination for class 12 economics paper throughout the country on April 25, while a fresh test for class 10 maths paper will be held only in Delhi, NCR and Haryana, “if at all”, in July. The CBSE decision came as students and their parents took to the streets across India to denounce the question paper leak and, in some cases, demand the sacking of the CBSE head Anita Karwal.
