New details have arisen in the latest controversy surrounding Hip Hop mogul 50 Cent and his G-Unit cohorts.

Fif was named in a lawsuit filed by the mother of a teenager Tony Yayo and his posse allegedly assaulted early last year.

According to Reuters, the lawsuit filed by James Rosemond and his mother Cynthia Reed, claims Universal Music Group -- owned by Vivendi SA -- and its labels Interscope Records, G-Unit Records and Shady Records, bear responsibility for the assault because they encourage artists to pursue violent, criminal lifestyles.

"The members of G-Unit, including defendants Yayo and 50 Cent, encouraged, sanctioned, approved and condoned its members threatening violence, and or engaging in violent acts in furtherance of its business," the lawsuit said.

It also states that the attack on Rosemond was intended to "promote and maintain Yayo and 50 Cent's 'gangsta' image," which was "promoted, marketed and advertised" by record labels.

Rosemond maintains that the unprovoked attack was a direct result of a shirt he was wearing which promoted G-Unit's rival rapper, The Game.

50 Cent, Violator Management, Violator CEO Chris Lighty, and Tony Yayo were all named in the suit.

Rosemond and his mother seek unspecified damages.
