Malkangiri: OMR sheets of the Mathematics paper of 108 students who had appeared for matriculation examination were found missing from a government-run high school in Malkangiri district on Sunday.

The complaint said the optical mark recognition (OMR) sheets of nearly 108 students, who appeared for Mathematics exam on Saturday, have gone missing from the school premises.
Malkangiri Superintendent of Police Jagmohan Meena said a team led by ASP U C Nayak has been sent to the school to conduct a thorough probe into the incident.

The matriculation examinations began on February 22 and would conclude on March 8. The Board of Secondary Education had earlier suspended 10 persons, including four examination centre superintendents, for their alleged role in spreading images of questions on social media.
