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, claims Malcolm Ausbon wanted $250,000 to stay quiet about a basketball court scrap last summer, 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 TMZ, 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.
