POLICE this afternoon renewed an appeal for help in the investigation into a crash in which four young men died.

Sgt Chris Simpson, the Thames Valley Police officer who is leading the investigation into the fatal collision which occurred yesterday on the A422 Brackley Road, Westbury, said: "Our condolences go out to all the families and friends of the victims involved in this tragic collision.

"At this time we are still in the early stages of an ongoing investigation. The driver plus three passengers were pronounced dead at the scene. We can confirm the 17-year-old man, who remains in a critical condition at the JR2, was a passenger, not the driver of the vehicle.

"Anyone who witnessed the collision or may have seen the blue Ford Fiesta prior to the collision is urged to contact us or Crimestoppers."

Anyone with information should contact PC Kelly Hobson via the 24-hour Police Enquiry Centre on 0845 8 505 505. If you don't want to speak to police or give your name, please call the Crimestoppers charity on 0800 555 111.
