A designer with Hong Kong Disneyland died and one of his colleagues was seriously injured when their car smashed into a tree outside the theme park on Lantau Island yesterday.
The dead man was named as 44-year-old Chung Wai-man.
He was cut from the wreckage by firefighters and taken to hospital with serious head injuries but was declared dead just after 1pm.
The front passenger seat where he had been sitting was badly crushed.
His 40-year-old colleague, who was identified only as Tsang, was last night said to be in serious condition in Princess Margaret Hospital, Kwai Chung.
Police said he had been formally arrested on suspicion of dangerous driving causing death.
The two-door convertible carrying the two Disney "imagineers" - a title used by people working in Disney's design and development branch - ran out of control after hitting the kerb at about noon.
It skidded for about 30 metres and spun round before mounting the central reservation and slamming into the tree.
The left side of the car took the brunt of the impact, an officer said, adding: "The 20-inch-wide (50cm) passenger seat was crushed to a width of just eight inches (20cm)."
Police are investigating whether the Toyota MR-S was exceeding the 50km/h speed limit at the time of the crash on Magic Road. Witnesses are asked to contact police on 3661 1346 or 3661 1300.
A spokeswoman for the theme park said they were saddened to learn of Chung's death, and help would be provided for his family and the injured man.
