Rhymes' former driver Eddie Hatchett, 39, filed a complaint against Busta Rhymes, born Trevor Smith, on Dec. 26.
"I don't know what set him off," Hatchett said. "I told him, 'I ain't scared of you. That's when his bodyguards grabbed me, and he punched and kicked me."
Hatchett, who drove Rhymes' Rolls Royce, Bentley and bulletproof GMC SUV, claimed that he was seeking the back pay because he couldn't afford a Christmas gift for his daughter.
"I didn't speak to my daughter for Christmas. I was embarrassed," he said.
He also accused Rhymes of owing several other bodyguards who have since been fired.
"For me to come out of my community like that and work for him days in a row, nights, not seeing my family, and not getting paid, and for him to act like that – I'll never put myself in that position again."
Hatchett said he had driven rappers N.O.R.E. and Foxy Brown without incident.
At press time, Busta Rhymes was out of the country, but he is expected to surrender to authorities for questioning today (Jan. 2).
Busta Rhymes is also facing assault charges for an August 2005 incident, in which his bodyguards allegedly beat a man for spitting on his Maybach as the luxury vehicle was passing by in Mid-town Manhattan.
Police still seek to question the rapper about his knowledge of a shooting in Brooklyn last February, that took the life of his bodyguard, 29-year-old Israel Ramirez.
