Seven people were injured when a truck collided with a bus and toppled onto its side at an industrial estate in Hong Kong on Friday, trapping passengers inside the goods vehicle.

Police said the crash happened at 10.28am, and the front of the truck hit the double-decker KMB bus playing route 98.

The truck driver was turning left from Chun Kwong Street onto Chun Cheong Street in Tseung Kwan O Industrial Estate, but lost control of the vehicle, hitting the side of the bus, which ran into the railing of the pavement, according to the force.

The glass windows of the truck were shattered. The 41-year-old driver and two male passengers, aged 39 and 49, were trapped in the vehicle but later rescued by firefighters.

A police spokesman said they suffered abrasions and chest pain.

The bus driver, a 55-year-old man, was also injured along with three male passengers, aged 32, 50 and 53.

All seven people were sent to Tseung Kwan O Hospital, the spokesman added. Later on Friday, a Hospital Authority spokesman said they had been discharged.

A police investigation is ongoing.

A KMB spokeswoman told the Post that after the truck lost control and toppled onto its side, “the bus driver immediately steered the bus away, but the flipped truck still crashed into the bus body. Three passengers on the bus and the bus driver were mildly injured.

The company pledged to offer assistance to the bus driver and fully cooperate with the police investigation.
