A man has died after two cars carrying members of the same family crashed into a river.
The 42-year-old was driving his 11-year-old daughter on the school run along a bridle path which runs near the Monsal Trail, north of the A6 in Derbyshire, when their Toyota Aygo veered off the path and became submerged in the River Wye.
A second car, a Toyota Rav4, driven by his 39-year-old wife and also carrying their nine-year-old son, was travelling just behind them before it too left the path and entered the water.
Derbyshire Police said the two children and their mother managed to escape unhurt from the cars but, despite desperate attempts by local residents, the father could not be saved and died a short time later.
Both mother and father were taking their children to school when the tragedy happened just after 8.30am on Thursday. A force spokeswoman said the children and their mother managed to safely get out of the vehicles and get to the shore.
Local people waded into the river to try to help the man and when police arrived on the scene an officer also plunged into the water to try to aid the rescue attempt. Emergency vehicles and personnel, including Derbyshire Fire and Rescue Service, local mountain rescue volunteers, land ambulances, and the air ambulance, attended to take all four passengers to hospital.
Police said the man later died at Stepping Hill Hospital. No names of the family members involved have yet been released and identification is expected to take place on Friday.
The force spokeswoman added: "Officers remain at the scene this afternoon and an investigation has been launched."
Paul Hawker, station manager at Derbyshire Fire and Rescue Service, was one of the first on the scene and said the wintry weather in the area was a contributing factor in the accident, said a fire service spokeswoman. He added that police were carrying out an investigation to ascertain the exact circumstances.
The county has experienced heavy snowfall and freezing temperatures in recent days.
