The 31-year-old victim was trapped beneath the bus and had to be freed by firemen. He died at Queen Elizabeth Hospital at 5.30pm. The 46-year-old bus driver was also sent to the hospital, while three pedestrians and eight bus passengers - five men and six women aged 23 to 72 - were sent to Kwong Wah Hospital.
