Raz B apparently has a brother named Ricky Romance. Yeah. At a concert in Atlanta last night, Ricky claimed he was attacked by security authorized by Yung Joc before his brother’s performance at the Salute The DJ’s Award Show.

According to Ricky, Joc’s security team stopped Raz in his tracks and refused to let him perform — all because Raz publicly dissed Yung Joc in a song a few months ago.

Ricky tells us he tried to help get his brother past the hired muscle … but Joc’s security wasn’t having it — and roughed him up pretty bad instead.
