A sessions court today rejected the bail plea of a 16-year-old student, accused of killing 7-year- old Pradhuman Thakur at the Ryan International School. The court had earlier reserved the order after hearing arguments of the counsel for the accused, the CBI and the complainant. The defence counsel had claimed that the charge sheet in the matter was not filed within one month, as prescribed in the Juvenile Justice Act, and he was not given required documents.
