Robert Marin, who owns LAX Jewelry Co., claims that he was beaten and robbed by 50 Cent's crew while in Las Vegas for the historic fight weekend, this according to TMZ.

Marin claims that he first met up with Fif at Drai's nightclub to show him a watch and chain worth $250k that he hoped to sell to the Queens emcee. He claims that the two parties stayed at the nightclub late into the night while negotioating a price, and to sweeten the deal 50 allegedly invited Marin to accompany him to Floyd Mayweather's gym.

Marin attests that upon arrival at Mayweather's gym the situation turned aggressive and dangerous. According to him, two goons from 50's camp first pistol-whipped him before stealing the jewelry and fleeing the scene. Since the purported incident, Marin has contacted Las Vegas authorities and filed a robbery report.

Scott Leemon, who serves as legal counsel to 50 Cent, contends that Marin has fabricated the entire story. "On behalf of 50, I can adamantly deny that he or his security had anything to do with these baseless and false allegations," Leemon said in a statement.
