Vijayawada:An intermediate first-year student died after suffering a severe head injury when he leaned out of the window of a moving APSRTC bus near the Annampalli toll gate in Mummidivaram mandal of Dr BR Ambedkar Konaseema district on Wednesday. As the bus approached the toll plaza, he reportedly put his head out of the window and sustained a serious injury after hitting a structure. The factory, owned by Kotaiah, caught fire following the explosion, which gutted raw materials and a vehicle parked on the premises. The child’s mother came to know of the deal and lodged a complaint with the police on January 23. Police traced the baby the same day and restored the infant to the mother.
