BREAKING - 4.40pm: The 49-year-old bus driver, from Birmingham, has been arrested on suspicion of dangerous driving.
A man has been killed and two others seriously injured in a crash after a coach, believed to be taking fruit pickers to Evesham, broke down on the M5 in thick fog.
The 35-year-old man from Birimingham was killed when the bus, on which he was a passenger, and a lorry crashed near Frankley Services.
Police said one serious injury was also from the bus and the driver of the lorry was also in a serious condition.
A total of 40 people were injured in the crash.
Chief Inspector Carl Flynn, of the Central Motorway Police Group, said the bus had broken down in a "live" lane of the M5 before the accident.
Addressing a news conference at a Highways Agency control centre near the crash scene, Mr Flynn said a 999 call was made by a member of the public reporting the stranded bus about 12 minutes before the crash.
He said: "At 6.12am a 999 call was made by a concerned member of the public about a coach having broken down on lane one of the M5 south.
"The Highways Agency did the appropriate signage on the network and dispatched their resources to the scene of the broken down coach as is normal practice.
"However, unfortunately at 6.24am a further call was received to say that a large goods vehicle had collided into the rear of the coach.
"Central Motorway police officers were immediately dispatched and arrived at the scene six minutes later and then assisted colleagues from the Highways Agency, the ambulance service and fire service to manage the scene."
West Midlands Ambulance Service was called to the incident on the southbound carriageway of the motorway between junctions 3 and 4.
Six ambulances, three ambulance officers, the rust’s Hazardous Area Response Team, three BASICS (British Association of Immediate Care Schemes) doctors, a medical incident officer doctor and two patient transport vehicles were sent to the scene.
A West Midlands Ambulance Service spokeswoman said: “On arrival at the scene crews found a coach and a lorry that had been in collision.
“A total of 40 adults were assessed and treated on scene. Twenty-seven of those have now been conveyed to hospitals around the region including Queen Elizabeth Hospital Birmingham, City Hospital, Alexandra Hospital and Sandwell Hospital.
“Unfortunately one patient, believed to have been travelling on the coach at the time of the incident, was confirmed deceased at the scene.”
The motorway was re-opened yesterday, police confirmed.
