A British tourist was killed and his friend was left in critical condition after a horror motorbike crash in Bali yesterday morning.

The holidaymakers were riding home from a night out in Buleleng Regency on the Indonesian island when a six-wheeler truck in front of them was said to have suddenly braked without warning.

The Brits, who were riding two motorbikes in the early hours of Wednesday morning, were unable to react in time.

They slammed into the truck's rear, the impact crushing their rented Honda Vario bikes, before they veered toward the roadside.

The truck driver reportedly fled the scene as passing motorists reported the horror crash to police.
