Football megastar David Beckham might be known for his sporting prowess, but he also takes his long-standing role as a Unicef goodwill ambassador very seriously.

As evidence of this, the 40-year-old was caught performing a small act of kindness this week by the good people of the London Ambulance Service.

• Beckham’s daughter hits with ‘dagger to the heart’

In a statement on Monday, the service revealed the former Manchester United player had treated one of its hardworking paramedics and her patient to a hot drink.

Senior paramedic Catherine Maynard, who works with the service’s Cycle Response Unit, was helping an elderly man who had fallen in the street in central London when she spotted Beckham.

“I was waiting with my patient for an ambulance to transfer him to hospital and although I was keeping him warm it was very cold outside,” she said.

“All of a sudden, I looked up and saw someone who looked like David Beckham walking past us. He said hello and got in his car. I said to the man I was treating, ‘I think that was David Beckham’.

“Ten minutes later, he came back with a cup of coffee for me and a tea for the patient.

“We were both very amused, and flattered. It was awful cycling around in the cold today and I couldn’t believe it when he came back with some hot drinks – I was so chuffed.”
