It came to the fore after an additional paper with solutions was recovered from the exam hall yesterday at Lahan-based Pashupati Adarsha Higher Secondary Exam Center.
Invigilator Brahmadev Mandal had informed Superintendent of the Exam Center Parmeshwar Raya after he found an additional paper with solutions in the exam hall.
"He ignored when I informed him about it," Mandal told Republica.
He has kept an answer-sheet with him.
Laxmi Prasad Adhikari, Chief of Higher Secondary Education Board, Lahan denied the allegation saying, "I did not find any such kinds of indecent activities as long as I was there in the exam hall."
It is also the duty of exam coordination committee to make the exams decent.
"If such an additional paper with solutions to questions were found inside the exam hall, it should be investigated and the guilty found should be brought to book," said Chairman of Exam Coordination Committee, Siraha, and Chief District Officer, Abdul Kalam Khan.
