The injured were admitted to a private hospital in Kunjithanni. Four students were later shifted to a hospital in Adimali for specialised treatment, officials said.

The accident occurred around 3 pm when the bus, belonging to St Sebastian's High School, Pottankadu, was returning after a Class 9 examination and a school programme. More than 30 students were on board at the time.

The mishap took place on the Desheeyam–Powerhouse Road, part of the Udumbanchola–Second Mile route, near Broadwin Resort. Preliminary reports said the driver lost control of the vehicle following light rain, causing it to ram into a compound wall. An electric post was also damaged in the impact.
