POLICE are to appeal to the nation for help in tracking down the truck driver who mowed down scooter rider Ron Cobbledick and left him to die.

On BBC1's Crimewatch next Wednesday 24th at 9.05pm motorway camera footage taken on the M40 at Henley near London of the truck responsible for the death of Mr Cobbledick, of Waterfoot, will be shown along with a reconstruction of the accident.

The truck has a red cab and blue bumper with an illuminated sign above the windscreen and lights on the front grille.

Mr Cobbledick, 43, died on October 30 when he was hit by four other lorries and a van. The trucker that knocked him off his scooter stopped only to remove the smashed bike from under his vehicle.

His wife Audrey, 63, of Burnley Road East and his family were unable to say final farewells to him because his injuries were so severe.

His step-son-in-law, Steven O'Brien, whose wife Lynda and son Jake, three-and-a-half, today moved to live with Audrey, urged everyone to watch the programme.

He said: "The police are undergoing a process of elimination. They started with 12,000 wagons and they are whittling them down every day but it is a slow process to trace the vehicle, trace the driver and check the tachograph.

"An accident is an accident -- the crime is that he stopped, removed Ron's bike and just left the scene. He didn't know if Ron was dead or alive and we do not know if he died instantly or was left waiting for the next truck to hit him.

"I can't get this out of my head. I want the trucker to come forward and explain it to us because we have so many unanswered questions."

He said his family were all avid viewers of Crimewatch and he hoped the reconstruction, which shows Audrey waving Ron off and features an interview with her, will trace the driver.

"Someone must have loaded that truck on a day-to-day basis," Steven said. "Someone must have seen it at a petrol station. The person driving it must have told someone what happened, if he has a conscience. Someone must know who he is."

He said Audrey was coming to terms with Ron's death slowly but she had good days and bad days. Weekends are hardest because that is when he would arrive home after working away at Lambert Howarth in London.

Motorcyclists and truckers have joined forces to try to track down the hit-and run driver by making posters that have been circulated locally and across the country.

The national Motorcycle Action Group is also offering a £5,000 reward to trace the driver of the truck.
