A mother of a Class VIII student allegedly poisoned to death her daughter's classmate, Bala Manikandan, 13, unable to bear with his better all-round performance, in a school at Karaikal in Puducherry.
The accused, identified as Sahayarani Victoria, was arrested on murder charges and remanded in judicial custody on Sunday.
The police said the woman was jealous of the boy's excellence in education and his active participation in cultural events. Sahayarani was reported to have hoodwinked the watchman of the school at Nehru Nagar on Friday into believing that she was delivering soft drinks to the boy at the bidding of his relatives, while the students were practising on the campus for the annual day function.
