Chris Brown has undergone a court-ordered year of domestic violence counseling and 50 hours community service following his 2009 attack on then-girlfriend Rihanna following the Grammy Awards. The sentence, which also includes an ongoing five years of probation, may not have rehabilitated the Sony Records star, as new allegations emerge.

TMZ.com reports that following Brown’s headlining performance at Power 105 Powerhouse on Saturday (June 21), he was involved in an altercation with a female at Anaheim, California’s Heat Ultra Lounge. Deanna Gines told the celebrity news site that Brown “shoved her to the ground.” Gines, asserting that the shove was the deliberate, filed a police report against the multi-platinum star.

The Anaheim Police Department did confirm to TMZ that a report was made, but did not confirm the victim’s name.

Gines also claims that based on her injuries sustained in the fall, she may require surgery—due to torn ligaments in her knee. She provided a picture to TMZ of herself in crutches.

Chris Brown’s rep, Nicole Perna, responded to TMZ with, “I’m unaware of the incident, as is Chris’ lawyer and his entire team.  He was in a great mood after Powerhouse.” She added, “None of this makes sense.”

If convicted of any crime, especially assault—which he was charged with in 2009, Chris Brown could face years in jail. Earlier this month, Brown dodged jail-time when his probation officer did not give him a violation for his January brawl with Odd Future’s Frank Ocean.

UPDATE: The owner of Heat Ultra Lounge is publicly defending Chris Brown. Although the owner’s name was not printed in the story, TMZ.com alleges that he contacted the site to clear Brown’s name. The owner claims that Deanna Gines was asked by security to leave the club. Further, he claims that police were called due to her disruption. “Heat staff and security did what they had to do,” said the man. “[Chris Brown] was a complete gentleman.”
