Luton-Dunstable Busway remains partially closed after a serious collision left three injured on Saturday night.
It is thought that a tyre puncture caused a bus to derail close to Kiln Way, at around 11pm.
The driver of the vehicle was among three injured in the incident.
Beds Police, East of England Ambulance Service and Beds Fire & Rescue were called to the scene, but firefighters’ assistance was not needed.
An Arriva spokesperson told the Luton News: “We can confirm that an Arriva bus was involved in an incident on the busway near the Skimpot roundabout on Saturday evening.
“Our driver and two other passengers were injured.
“An investigation has now commenced into the cause of the incident.
“The busway remains closed between Skimpot and the White Lion retail park until minor repairs can be carried out.”
Luton Borough Council has said that it is “working with Arriva to investigate the cause of the incident.”
