A CRASH involving a police car and an ambulance left four people injured and closed a Burton Street for hours.
The police car collided with the non-emergency private ambulance in Shobnall Street at the junction of Casey Lane, in Shobnall, causing the ambulance to overturn.
Staffordshire Police confirmed officers responded to an incident at 9.45pm on Wednesday.
The road was closed while an examination of the scene was carried out.
Two members of staff in the ambulance and the two police officers in the car suffered minor injuries and were treated by West Midlands Ambulance Service at the scene and taken to Burton's Queen's Hospital for treatment.
Witnesses said the police car was involved in a high-speed chase with a silver Porsche, but this has not yet been confirmed by officers.
Rosemary and Rinaldo Buoniconti live just yards from where the accident happened in Shobnall Street.
Mrs Buoniconti said: "We were watching a film and heard a loud noise.
"We came out and saw the ambulance on its side – the police car must have been going at some speed to knock it over.
"There's always police going up and down the street but we didn't hear any sirens this time."
Bill Ganley runs the Grange Inn in Casey Lane.
He said: "I didn't see the crash but staff at the pub told me that a Porsche came flying around the corner of Byrkley Street at speed and went off towards Rangemore Street.
"A few minutes later two police cars came the other way.
"Me and my wife were at home. It sounded like two explosions – I suppose the car hitting the ambulance and it falling over.
"The Porsche was abandoned at the back of a house in Grange Close."
Another resident told the Mail his son called the emergency services following the crash and that police arrived on the scene shortly afterwards.
An investigation into the collision is under way and police are asking witnesses to call 101, quoting incident number 735 of July 30.
