West Ham striker Demba Ba claimed on Tuesday he'd been racially abused by a fan after police were called to the club's end-of-season dinner at a luxury London hotel.

Ba said the trouble at the Grosvenor House Hotel on Monday started when he was subjected to racist comments from an unhappy fan the day after the London club's relegation from the English Premier League was confirmed.

There had been reports tempers frayed when Senegal striker Ba, on loan from German club Hoffenheim, refused to sign an autograph.

However, Ba insisted he did sign and he and West Ham teammate Danny Gabbidon had been subjected to racist abuse.

"It was a crazy situation," Ba told Talk Sport Radio on Tuesday. "This guy came to me when we were sitting at the table. There were two players per table and Manuel da Costa was with me.

"This guy came and asked for an autograph so I gave him his autograph. Then he asked me nicely how I was feeling so I just said I was tired from the game yesterday and that it was a tough game. And then he just replied 'Oh, we're tired of watching you play every weekend'."
