British bike teenager dies in crash.
British rider Ashley Martin suffered a major head injury when he crashed at Cadwell Park in Lincolnshire on Sunday during the event, which attracts thousands of motor-sport fans.
After he received extensive treatment at the circuit, Martin was airlifted to Leeds General Infirmary where he later died, officials said yesterday.
The 18-year-old rider, who is from Shiptonthorpe, East Yorkshire, was taking part in qualifying for the British Supersport Championship race - one of the subsidiary attractions to the main British Superbikes event.
He was on a section of the circuit known as the Gooseneck when the accident happened.
A statement from the Motorcycle Circuit Racing Control Board yesterday said: "MCRCB-Events regret to announce that Ashley Martin, aged 18, from Shiptonthorpe, Yorkshire, has died in hospital.
"He was unconscious at the scene after suffering a major head injury. He sadly succumbed to his injuries early this morning.
"The circumstances of the incident will be subject to investigation by the Motorcycle Circuit Racing Control Board and the relevant authorities.
"Our thoughts and profound sympathies are with the family and friends of Ashley and when appropriate we will be seeking instruction from them as to how to provide the best possible tribute."
The news came just before racing began yesterday.
