Sydney, July 14 : John Steffensen, who is the current Commonwealth Games champion, has accused Athletics Australia (AA) of racism after he was left out for an individual 400m spot at the London Olympic Games.

Steffensen launched a Twitter attack against AA on Friday and threatened to boycott the Olympics after rising teenage star Steve Solomon was given the only available position.

"I''ve put up with being racially vilified by this federation, being discriminated against on many teams. You know it''d help if I was different colour, then a lot of decisions with my federation would be totally different, but I''ve never brought that up, I''ve always kept quiet on that," News. com. au quoted Steffensen, as saying.

"But it is the fact, it''s the way it is, but I live with it and I keep running and I keep representing my country and I keep winning Australian trials," he added.

Steffensen last night vented his anger on Twitter suggesting he might withdraw from the Games, giving up his position in the 4x400m relay team.

"I dnt want no handouts cause I didn''t earn my spot!! But if they put another ath ahead of me then I''m pulling out the games!!," he tweeted.

Steffensen defeated Solomon in the Olympic trial in March before getting injured in the final of the Stawell Gift, with the hamstring injury coming back to haunt his London preparations. (ANI)
