India arrests hundreds over Bihar school cheating
About 300 people have been arrested in the Indian state of Bihar, authorities say, after reports emerged of blatant cheating in school exams.
Cheating is reportedly common in Bihar exams but rarely seen on this scale
Parents and friends of students were photographed climbing school walls to pass on answers.
Many of those arrested were parents. At least 750 students have been expelled.
An estimated 1.4m students are taking their school leaving exams in Bihar alone - tests seen as crucial for their chances of a successful career.
The authorities have clearly been embarrassed by the cheating, the BBC's Jill McGivering says, with the episode prompting ridicule on social media.
Students were seen copying answers from smuggled-in note sheets, and police posted outside test centres were even seen being bribed to look the other way.
One official warned parents they were harming their students by helping them cheat
Hundreds of students have been expelled following the reports
On top of the arrests, in four centres further exams have been cancelled.
Bihar Chief Minister Nitish Kumar condemned the cheating but said the images were not the "whole story" of his state.
He warned parents that helping their children cheat would only harm them in the long run.
State Education Minister PK Shahi said it would be difficult to conduct fair exams without help from parents, given the potential number of people involved.
"Three to four people helping a single student would mean that there is a total of six to seven million people helping students cheat," he said.
"Is it the responsibility of the government alone to manage such a huge number of people and to conduct a 100% free and fair examination?"
