While Chris Brown sits in a jail cell, his legal battles continue to mount. However, he's fighting back. The R&B singer is countersuing a basketball player for extortion.

According to TMZ, Brown is suing Malcolm Ausbon over an alleged fight that happened during a pick-up basketball game at a Los Angeles gym.

Ausbon originally sued Brown claiming he assaulted him over a foul call and then proclaimed he was affiliated with the Bloods gang. Ausbon also alleges that he sustained injuries all over his body and had to be hospitalized.

The 'Loyal' singer, who was recently sentenced to 131 more days in jail for violating his probation, denies that he attacked Ausbon.

Brown's suit alleges that Ausbon knew he was falsely accusing the singer but his attorney later sent in this written demand:

Mr. Ausbon believes $250,000 will suffice compensating him for his physical and emotional injuries. Mr. Ausbon is placed in a position by the LAPD where he needs to decide whether he will press charges for aggravated assault and battery. However, Mr. Ausbon prefers not to resort to filing these claims or the lawsuit. He would rather be compensated."

Mark Geragos, Brown’s lawyer, said Ausbon promised to keep the incident a secret if Brown coughed up the money, but the singer refused to pay.

Attorneys for Malcolm Ausbon had no comment on the matter.
