NINETEEN people have been killed and dozens injured in Hong Kong’s worst traffic accident since 2003.

A double-decker bus, which is thought to have been speeding, lost control and crashed in a local suburb, according to city authorities.

Passengers who were on board the bus have been quoted by local media as saying the double-decker was full and travelling very fast.

Local police have launched an investigation and have arrested the driver on suspicion of dangerous driving.

The crash left 15 men and four women dead and sent more than 60 others to hospital.

Photos and videos, published by local media or posted on social media, showed the bus lying on its side while emergency workers treated injured passengers.

TV channels broadcast footage of rescuers cutting open the roof of the bus, operated by the Kowloon Motor Bus Company. Viewers also saw images of the bodies of passengers, laid out on the ground, covered in white sheets.

Multiple passengers, interviewed by the TVB and Cable TV news channels, said the bus was speeding.

None of the passengers that were interviewed were identified by name.

The South China Morning Post newspaper reported that the crash was the Asian financial centre’s deadliest traffic accident since a 2003 bus crash killed 21 people.
