A child was brazenly abducted this morning from his school bus by unidentified bike-borne persons who also shot at the driver when he tried to stop them, police said. The incident took place at a time when there is an unprecedented security cover in place in the national capital in view of the India-ASEAN commemorative summit and the Republic Day celebrations. The incident took place around 8 am in east Delhi when the boy was in the school bus along with 20 other students, including his elder sibling, officials said.
