The driver of a double-decker bus that overturned in Hong Kong killing at least 19 people and injuring more than 60 was arrested on Saturday evening for dangerous driving, police said.
Images from the scene showed rescuers trying to reach passengers trapped inside the bus, which lay on its side with part of its roof torn off near the town of Tai Po in the northern New Territories.
It appeared to have slid on its side and hit a lamppost which smashed into the upper decks of the vehicle. The driver has been arrested on charges of causing death and grievous bodily harm by dangerous driving.
In an updated toll in the early hours of Sunday morning the city's Hospital Authority said another victim had died, bringing the total to 19 fatalities.
But ten of the injured were in critical condition, while another 20 were seriously wounded, officials said.
Most of the dead and injured were on the upper deck of the bus, Chan Hing-yu of the fire department told reporters.
The driver was suspected of being over the speed limit as he went down a slope and lost control of the vehicle, senior traffic superintendent Lee Chi-wai told reporters.
He was not in need of any medical treatment after the crash and was be sober, he added.
