Man, 72, critical after being hit by runaway truck in Ho Man Tin
Another two suffer minor injuries after truck under tow careers downhill

Three people were injured when a nine-tonne truck under tow broke free and careered 80 metres downhill.
The truck was being pulled up a steep street in Ho Man Tin shortly before 9am yesterday when two harnesses securing it to the tow vehicle snapped.
A 72-year-old man was in critical condition last night after being hit on the head by debris as the truck mowed down a traffic light and railings on a safety island before crashing into a wall and toppling on its side.
A woman who saw the accident said the elderly man had been alone on the safety island.

"It appeared he saw the truck coming but he was apparently frozen in position when the vehicle crashed into the safety island," she said.
A 22-year-old student who tripped and fell as he ran from the truck, and the tow vehicle's driver, who tried in vain to jump into the truck to pull on the handbrake, suffered minor injuries.
