A cab driver who spent Christmas Eve driving miles to find an elderly woman who left thousands of dollars in his taxi has refused any reward. Mohammad "Mukal" Asaduzzaman travelled nearly 80km (50 miles) to return more than $21,000 (£13,000) to a forgetful Italian grandmother. Felicia Lettieri, 72, was in New York to visit relatives when she left the cash in his taxi outside the city's Penn Station. Police had told Ms Lettieri not to get her hopes up that she would be reunited with her money, which was the travelling fund for her and six relatives, as well as passports and jewellery. But while a lesser man might have been tempted to keep such riches, Mr Asaduzzaman, 28, took the high road. The Bangladeshi driver, who is a pre-medical student living in Queens, spent hours searching for his errant passenger. When he found no-one in at the Long Island address he found in her purse, he left his phone number and returned later with the money. Ms Lettieri said of his actions: "It was so beautiful, so kind." Mr Asaduzzaman, an observant Muslim, told the New York Post his philosophy: "When I was five years old, my mother told me, 'Be honest, work hard and you will raise your station.'"
