Is beating up a 14-year-old a new low in irrational rap rivalries gone worse? On Saturday, rapper Tony Yayo, who is also a member of 50 Cent's G-Unit, turned himself into police. Yayo and some other men were accused of assaulting a 14-year-old boy on 25th Street. And it wasn't just any regular 14-year-old boy - the boy happened to be the son of Jimmy "Henchman" Rosemond, head of a rival music management company Czar Entertainment, and the boy was wearing a shirt with a Czar logo on it.

On Tuesday night, the rappers were leaving their record company on West 25th when they saw the boy. According to the Post, Yayo, aka Marvin Bernard, asked how old the boy was, and when he responded, Yayo said, "I don't give a f*** how old you are - F*** Czar Entertainment!." Plus, another man held out a gun as Yayo "made sure the victim knew who he was before taking off." The boy also reportedly said he saw 50 Cent in the SUV, though 50's lawyer says the rapper was not in NY State during the incident.

The boy's mother Cynthia Reed told All Hip Hop, "As a mother I am concerned that my son, who is a fan of hip-hop, would be attacked by the same artist whose music he listens to. It's a shame that 50 Cent and Tony Yayo could feel comfortable slapping and physically attacking an innocent 14-year-old minor that they market and promote their records to."

Yayo was released on $5,000 bail.
