In a stern message, Delhi Chief Minister Arvind Kejriwal told the principal of Rabia Girls Public School, Naheed Usmani, that punishing kindergarten children for alleged delay in payment of school fees is "unacceptable." On Thursday, Mr Kejriwal and his deputy Manish Sisodia visited the school, where 16 little children were confined in the basement for non-payment of fees. He also assured the parents that stringent action will be taken against the school authorities.
