The neighbours of the family involved in the river tragedy when their cars left the road and plunged into a river killing dad David Cox say they heard shouting 'Daddy is trapped'.
Neighbour Victoria Bamber said Mr Cox's son came running down the country lane shouting for help to free his father.
"He came banging on the door saying 'There's been an accident, Daddy is trapped'.
"When I got to the scene, I could only see the silver 4x4 upside down in the water and Ruth was desperately trying to find David."
Mrs Bamber said she and others waded into the freezing cold water to try to free Mr Cox, smashing the window with a large rock so the central locking failed and the car doors would open.
It is thought daughter Tess escaped through the rear window which had smashed.
A police officer who arrived on the scene also waded into the water to help but, despite the efforts of emergency services personnel, Mr Cox could not be saved.
The head of the BBC has paid tribute to employee David Cox who was killed in Derbyshire yesterday when his car left the road and overturned in a river while he and his wife took their children to school.
Mr Cox and his wife Ruth were driving their children Tess, 11 and Loan, 9, in separate cars when they both skidded off of the road and into the River Wye.
Tess managed to escape her fathers car after around 4o minutes and get to the riverbank as did wife Ruth and Loan.
Despite neighbours launching a desperate rescue attempt to try and free Mr Cox he later died in hospital.
Acting BBC Director General Tim Davie praised Mr Cox's role in the corporation's coverage of the London 2012 Olympic Games.
"We are very sad to learn of David's tragic death. He was a popular member of the Future Media team in Salford and had been key to the success of the red button service during the Olympics in the summer.
"Our thoughts are with his family, friends and colleagues here at the BBC at this difficult time."
