A one-and-a-half-year-old boy died while undergoing treatment following a road accident involving an e-rickshaw in Birgunj on Wednesday.

The e-rickshaw that was being operated by Ramsundar Das Tatma, 35, lost control and overturned while making a turn near the Townhall in Birgunj Metropolitan City-10, injuring the child and his father, Rajeev Kumar Mali of Panitanki in the metropolis.

The father-son duo sustained serious injuries on their heads and noses and were taken to Birgunj-based Advance Hospital for treatment.

The hospital referred the child to National Medical College in the city after the medical personnel at the Advance Hospital could not stop the nosebleed.

The child succumbed to his injuries while undergoing treatment, police said.

The police have arrested the driver for further action.
