A group of students on Saturday staged a demonstration near the Central Board of Secondary Education (CBSE) office at Preet Vihar here against the leak of Class X Mathematics and Class XII Economics papers.
"The students tried to block the road in front of the CBSE office, but we kept them away. A group of about 25-30 students are protesting outside the CBSE office," said a senior Delhi Police officer.
The board has announced a re-examination of the Class XII Economics paper on April 25, while the re-test for the Class X Mathematics paper is likely to be conducted in July.
Education Secretary Anil Swarup said on Friday that a preliminary enquiry had revealed that the leak for the Class X Mathematics paper was restricted to Delhi and Haryana.
Two cases have been registered in the paper leak incident so far. The Crime Branch of Delhi Police has questioned nearly 60 people, including students and tutors, in this connection.
