A 58-year-old motorcyclist died after losing control of his vehicle and overturning inside Hong Kong's Eastern Harbour Crossing early Thursday, police said.
Police said the accident occurred in Kwun Tong shortly after midnight at about 12.51am as the motorcycle was travelling through the tunnel towards Hong Kong Island.
The vehicle is believed to have struck the left-side kerb before skidding forward and overturning. The rider, a 58-year-old man surnamed Woo, suffered serious head injuries and was rushed to United Christian Hospital in Kwun Tong.
He was pronounced dead at 3.46am. The case was later reclassified as a fatal traffic accident, with the Kowloon East Special Investigation Team of Traffic taking over the investigation.
