Police are investigating an incident on the M40 this morning, which caused an Oxford Tube coach to overturn.
At about 2am today, the coach was travelling between junctions 3 and 2 southbound, when it overturned.
Twelve passengers and the coach driver were onboard. One passenger was taken to Wexham Park Hospital in Slough with a possible back injury. Police said that passenger was expected to be released from hospital later today.
A police spokesman said: "Shortly after the incident, officers arrested a man nearby, who had left the scene. It is believed he may have had some involvement in the cause of the collision.
"The man, who is 21 years old and from Oxford, remains in police custody."
Two lanes of the motorway were closed until about 9.45am to allow officers to begin their investigation and for the vehicle to be recovered.
