Tyres of about 50 vehicles, including 36 buses, are burst, with hundreds of passengers affected

Tyres on about 50 heavy vehicles were damaged by a single screw sticking up from the road surface yesterday, delaying traffic for more than three hours.
The incident involved buses, trucks and coaches on a section of Tuen Mun Road, near Yau Kom Tau, travelling in the direction of Tuen Mun.
KMB confirmed a total of 58 tyres on 36 buses were damaged after running over the screw and hundreds of passengers had to be transferred to other buses. No one was injured.
The Highways Department said inspectors had not spotted the protruding screw, and apologised.
A KMB spokesman said: "About 40 bus trips were severely affected and the damaged buses all needed to be immediately repaired."
The spokesman added: "If it is a case of … negligence of a third party, KMB will proceed with recovery action for its losses, including those incurred by the cancellation of the 40 aforesaid bus trips, against the responsible parties."
