British track and field star Mo Farah was "humiliated" at a US airport on his way home from the Rio Olympics in August, his wife has alleged.
Tania Farah said her husband was forced to the back of the queue by a Delta Airlines attendant with a "sad little life".
The staff member allegedly yelled at Mr Farah and would not believe he had a business class ticket. It happened in Atlanta, as he was heading to Portland, Oregon with his family.
"This woman basically humiliated him until people came forward and said: 'That's Mo Farah, the Olympic champion'," Ms Farah told the Sunday Telegraph.
"She was mortified afterwards, but had basically yelled at him.
"He was the only black person and hadn't done anything to warrant it."
However, the Sun has reported the incident actually involved a "foul-mouthed rant" from Ms Farah toward the attendant, when the family were late to board the plane.
Mo Farah won gold in the Men's 10,000m and 5000m races at the Rio Olympics.
