John Galliano's future at Christian Dior looks uncertain as police earlier questioned the British fashion designer for several hours over accusations that he hurled racial abuse at people in a Paris bar.

One of the world's top designers, Galliano was suspended by Dior on Friday hours after a couple complained he shouted racist and anti-Semitic insults at them while out drinking in Paris's hip Marais district.

His lawyer said Galliano, who lives in Paris, denies making the comments.

But speculation about his future raged after a new complaint was lodged about a similar incident in October and a British tabloid posted a video clip of what it said was Galliano making offensive remarks.

Galliano ignored questions on Monday as he strode through a crowd of reporters outside a police station in central Paris, his face largely hidden by a wide-brimmed black hat as he emerged from a Land Rover. He was inside for more than five hours.
