KATHMANDU: The government has directed Nepal Police's Central investigation Bureau to look into probable foul play after question papers of Compulsory Science and Social Studies in the Secondary Education Examination (SEE) in Province 2 were leaked.

Education Minister Giriraj Mani Pokharel on Friday said that the CIB was entrusted the responsibility to investigate how question paper of the aforementioned subjects was made public prior to exam hours.

The National Education Board (NEB) cancelled the test after leakage of Social Studies question paper through social networking sites including Facebook in Janakpur last night. Yesterday, the Science test was called off after the question paper was leaked in Saptari district through Facebook.

Meanwhile, clashes erupted between security forces and SEE students who resorted to vandalism in Birgunj after the cancellation of their tests. The situation became tense after the police used water cannon and tear gas shells at the mob in a bid to avert vandalism.

Nonetheless, a vehicle (Na 1 Ja 7787) was vandalised in Birgunj while the SEE candidates and students obstructed transportation along the East-West Highway at Chandrapur road section in Rautahat district.

The SEE  will run till April 4 and the authorities are yet to reschedule the cancelled exams.
