An elderly couple have sustained serious injuries following a collision in Milton Keynes.
Thames Valley Police is now appealing for witnesses of the incident.
Shortly after 3pm on Tuesday (October 18) a silver Vauxhall Astra and a silver Vauxhall Insignia crashed on the V6 Grafton Street at the junction with Grampian Gate, Winterhill.
The driver of the Vauxhall Astra, a man, and a woman, who was a passenger, both aged in their nineties, were released from their vehicle by fire crews and sustained serious injuries.
They were taken to Milton Keynes General Hospital by South Central Ambulance Service where the man remains.
The woman is currently at the John Radcliffe Hospital.
The driver of the Insignia, a man in his thirties, was taken to Milton Keynes General Hospital with minor injuries and was discharged on the same day.
Officers are investigating the circumstances and the forensic collision investigation Unit attended and examined the scene.
Investigating officer PC Neil Stephenson, said: “I would like to thank the public for their patience and understanding as the V6 Grafton Street remained closed for nearly three hours to allow the investigation to take place.
“I would like to speak to anyone who witnessed the collision or who may have seen either vehicle prior to the collision or any parked vehicles on the slip prior to the collision.”
Anyone with any information about the incident should contact the 24-hour Thames Valley Police enquiry centre on 101 quoting URN 907 18/10.
