HONG KONG - The winner of Beijing's half marathon He Jie and three African runners have had their results cancelled after an investigation found that the three slowed down near the line allowing the Chinese athlete to finish first, organisers said on Friday.

He had won the race held last Sunday in China's capital in a time of 1:03:44, a second ahead of Ethiopian Dejene Hailu Bikila, and Kenyans Robert Keter and Willy Mnangat, who tied for second place.
