Boy died of neck injury on world's largest water slide

A 10-year-old boy who was killed while riding the world's tallest water slide died of a neck injury, US police have said.

Caleb Schwab was one of three passengers riding in a boat on the 168ft Verruckt water slide at Schlitterbahn Waterpark, near Kansas City.

Emergency responders said they arrived to find the boy dead in a pool at the end of the ride.

Police say two women - not related to the boy - who were also in the special boat used in the ride sustained minor facial injuries, and were treated at local hospitals.
