The son of singer Engelbert Humperdinck has completed a marathon to raise funds for his father's charity.

Bradley Dorsey hopes to raise more than £2,000 for the Derbyshire, Leicestershire and Rutland Air Ambulance with the run.

The 36-year-old took part in the Los Angeles Marathon to raise money for the charity, of which his father is patron. Bradley, who was born in Leicester but now lives in LA, said: "It was the best positive moment in my life and to have raised over a thousand pounds for one of my father's favourite charities felt amazing."

The runner said that his sister, Louise, was rescued by Texan air ambulance crews, in 2008, when her car hit a stag and rolled down a mountain.

Air ambulance fund-raiser Barbara Parish said: "His support is much appreciated."
