Troubled R&B star Chris Brown is counter-suing a sports fan for extortion, insisting he threatened to tell the police the singer started a fight unless he paid him off.

Brown, who is currently behind bars after pleading guilty to violating his probation by fighting with a 20 year old outside a Washington, D.C. hotel last year (13), claims Malcolm Ausbon wanted $250,000 (Gbp156,000) to stay quiet about a basketball court scrap last summer (Jul13), which Brown insists he was not part of.

Ausbon previously sued Brown claiming the singer attacked him during a pick-up basketball game at a Los Angeles gym.

In Brown's new counter-suit, which has been obtained by, the star's lawyer, Mark Geragos, claims Ausbon promised to keep the matter secret if Brown paid up. When he refused, the plaintiff filed suit.
