The Delhi Police's crime branch is investigating the alleged leak of Class 12 economics and Class 10 mathematics papers after registering two separate cases in the matter. The CBSE filed a complaint with the Delhi Police saying that they received a complaint by fax on March 23 from an unknown source that a man running a coaching institute in Rajinder Nagar was involved in paper leakage. The complaint also named two schools in Rajinder Nagar for their involvement in the alleged leakage. The Delhi police detained the owner of the coaching institute Vicky Wadhwa and are interrogating him. But the students of the institute are saying that Vicky Wadhwa is being made a scapegoat and that he had no hand in the paper leak.
