Typing 'anti-national' into Google Maps search bar on Friday yielded a map of Jawaharlal Nehru University (JNU) campus here, with a photograph of an entrance to the varsity on the left hand side.It is unclear what caused the glitch in the world's largest online search engine, but it has certainly not gone down well with some students and faculty who said they would approach Google India about the problem, according to media reports. JNU has now, for many weeks, been involved in a controversy over what constitutes anti-national words and deeds.The JNU Students' Union president Kanhaiya Kumar and two other students were arrested on charges of sedition. All three were granted bail earlier this month.They have been accused of raising anti-national slogans at a cultural event organised on the campus on February 9 to commemorate the third anniversary of the execution of parliament attack convict Afzal Guru.
