In this video from 2006 Bouya Mayola was claiming that Koffi had stole his money and Koffi is sick in his head (because he wanted to sleep with his brother daugther, etc.) with Luxene Musengi saying that Koffi signed a pact with the devil and that he had a debts to pay to Mr. Frank.

there is some truth in it,i cant comment much on the part about koffi sleeping with family members,but the rest clearly koffi has been involved in almost every type of controversy which exists,and it goes from cases like the one with diego music and much much minor stuff than that or recently the two mabanga affairs to cases like the one of marc tabu for example
lol like a friend of mine says when you hear koffi did something you have to ask yourselves which of the koffis he has in himself did that,the  very intelligent and serious koffi,or the very funny koffi,or the strong character koffi or the very evil koffi

I heard that affaire with his brother daugther was true and that also one of the reasons was that his ex'wife Ma'gode broke up with him
