David Darnell Brown, know to the hip hop community as Young Buck; is wanted in connection with a stabbing at Monday’s Vibe Awards outside of Los Angeles. The assault followed a brawl that erupted when a man attacked Dr. Dre as he was about to get a lifetime achievement award.

Detectives were negotiating with a lawyer representing G-Unit rapper Young Buck but had not yet reached a surrender agreement, Santa Monica, Calif., police said Thursday.

Young Buck’s mother says her son has been treated unfairly by police and demonized for his gangster rap songs that reflect street life.

“Yes, he is into gangsta rap, but that doesn’t make him a criminal,” Audrey Horn told The Associated Press on Thursday from her home in Nashville; Young Bucks hometown.

“The Santa Monica police have been unfair to David because he’s been treated like a real live criminal when the man who attacked Dr. Dre is being treated like a victim,” Buck’s mother said.

In a videotape of the ‘fight’ Young Buck is shown with a knife in hand. The assault apparently occurred after a man who approached Dr. Dre and tried to punch him.

Jimmy James Johnson, a 26-year-old from Los Angeles suffered a collapsed lung and was hospitalized in stable condition.

After the ruckus, police said Young Buck fled the Santa Monica airport hangar where the show was being taped. Young Bucks mom said her son did not flee from police, but simply left with Dre and others.

Drug offenses, domestic assault, reckless driving. openly discussing his past as a drug dealer, saying he was shot in the arm and thigh at age 19 is Young Bucks past. His mother says the domestic assault charge stemmed from an argument between Buck and his girlfriend and was later dropped.

Young Buck pleaded guilty to two counts of possession or casual exchange of a controlled substance, both misdemeanors. The other cases were dismissed or their outcome not immediately available.

Young Bucks mother says “He’s never been charged with being violent or shooting or killing anyone.”

Santa Monica Police Lt. Frank Fabrega said detectives had been in contact with Scott Leemon, an attorney representing the rapper, but had yet to reach an agreement.

“We’re encouraging him to surrender,” Fabrega said.

Leemon, a New York attorney, issued a press release saying Young Buck, would “surrender in the near future and then be released on bail.”

Leemon, reached by phone, confirmed the statement but declined to provide details.

Police investigators are trying to identify two other men seen holding knives in a videotape of the fight that followed the attack on Dr. Dre.
