A former kitchen porter at one of Gordon Ramsay's restaurants is taking the chef's company to an employment tribunal alleging he was the victim of racial harassment and unfair dismissal.
Tama Siby, 26, claims that he was singled out for abuse because of his religion and was once called a "black donkey" by a fellow employee.
Meanwhile, other incidents of alleged discrimination include preventing Mr Siby from observing his fasting period by barring him from storing yoghurt in the refrigerator.
He is seeking damages of over £50,000 in the case, in which Mr Ramsay is not implicated.
Commenting on his decision to pursue legal action, Mr Siby told the Mirror: "It has nothing to do with money - it has to do with what is right and what is wrong. I want to stop them doing this to others.
"I work very hard, but nobody should have to put up with this kind of treatment."
Mr Siby's case will be heard at the London Central Employment Tribunal.
