A British student who worked for U.S. retailer Abercrombie & Fitch Co. in London said Wednesday she was discriminated against because she has a prosthetic arm.

Riam Dean is seeking up to 25,000 pounds ($47,000) in damages at an employment tribunal.

Dean, a 22-year-old law student at the University of London, told the tribunal she worked at Abercrombie's store on London's posh Saville Row and had been given permission to wear a sweater to cover her prosthetic arm.

After a few days Dean said she was told she was breaking the company's "look policy" and was asked to work in the stockroom.

Dean said the company gave new employees a thick guidebook dictating everything from how employees should wear their hair to the length of their fingernails.

'Not a cosmetic'

"I have worn a prosthetic arm since I was three years old," she said. "It was part of me, not a cosmetic."

Abercrombie & Fitch said in a statement it "has a strong anti-discrimination and anti-harassment policy." It said Dean's account of what happened was inaccurate.

The New Albany, Ohio-based company is known for its edgy advertisements and shops with a nightclub atmosphere. It has faced criticism in the past by those who claim it deliberately selects young, good-looking people to work in its stores.

In 2004 it spent $50 million US to settle a number of employment discrimination lawsuits in the United States.

The hearing began Wednesday and is expected to last for three days.
