Bizzy BoneBone Thugs-n-Harmony rapper, Bizzy Bone, is currently under investigation in Chicago for an allegedly assault on two fans following a concert last week.

According to TMZ, the rapper (real name: Bryon Anthony McCane) flipped on two fans, who police say, paid $80 each for a meet-and-greet with the members of the group on their tour bus last Thursday night (June 9).

But when the two men entered the bus, Bizzy flipped out.

One fan tells cops that a screaming match took place, which quickly escalated … and Bizzy began throwing punches.

The rapper allegedly hit both men until another member of the group stepped in and broke things up.

While police didn’t see any serious injury, aside from bruises, one of the men claims he suffered a broken nose.

One of the men filed a police report against Bizzy the following day.

At press time, Bizzy had not spoken to police, but they are investigating the matter.

Bizzy’s camp has not commented.
