An innocent producer was minding his own business on the set of rapper Game and R&B singer Chris Brown‘s new video in Los Angeles when he was robbed of over $12,000 in cash and jewelry at gunpoint.

Law enforcement sources tell us the armed robbery went down Tuesday in South Los Angeles — and the producer was sitting in his car with another person when 2 black male suspects walked up, pulled out a gun and demanded the goods. They made off in a gray Nissan Altima.

Sources on the music video shoot say the producer — named Mars — had walked about a block from the set when it happened. We’re told the suspects took his jewelry and his wallet … which was stuffed with a couple thousand bucks.

Chris Brown and The Game were on set at the time of the robbery, but were not near Mars. A rep for Game said nobody on set saw the incident go down — and that everyone on set usually has security when they walk around.
