The John Gotti book called Mob Star (one of the best mob books ever written) talks about this. More less the black dude snuck Gotti and got several punches in. Not really a fight. A big bounty was put on the black guys head (over a million dollars) that he had to be moved out of the prison to another location. After he go released from jail he went into hiding
Actually , i heard that he had went on to kill a cop upon being released.
