Earlier on Thursday, the Delhi Police held a teacher of a private coaching centre into their custody and questioned him in connection with CBSE paper leak.

Vicky, according to sources, is the owner of a Delhi-based Vidya Coaching Centre. Vicky did Bachelors in Computers from the Delhi University. He passed out in 1996.

Vicky was held following a series of raids launched by the Delhi Police's Crime Branch, which is examining how the exam papers were leaked.

 Following Students uproar, The Delhi Police has formed a Special Investigation Team (SIT) to probe the paper leak. Officials earlier said that initial inquiry had suggested that the papers were leaked a day before the Class 10 mathematics examination.

Ahead of recent controversies, Congress President Rahul Gandhi on Thursday tried to corner the Prime Minister Narendra Modi-led government by unfolding the "leaks" that had taken place during its term.

The papers of the Economics exam of class XII, held on March 26 and Maths exam of class X, held on March 28 were leaked on social media hours before the examination.

Soon after this, CBSE announced re-examination and a police investigation into the matter.
