*Bone Thugs-n-Harmony member Bizzy Bone (pictured) is back at it again. This time, some drama ensued in Chicago while after a concert last week.

TMZ reports that the rapper, who has a track record of mental illnesses and addictions, punched two fans after the performance, during meet-and-greet Thursday night (June 9). The two fans actually paid $80 for the extra benefit.

According to claims, he “flipped out” as he entered the bus and refused to sign autographs. He then began shouting at the men and eventually introduced his good hand to his fans.

One victim suffered a broken nose, while the other walked away with just bruises. For an eyewitness account of the incident, go here.

Police confirm that one fan filed a report and the complaint is currently being investigated.

Maybe the craziness associated with the group is what drove Krayziee Bone to leave.
