Not seen the documentary but Im sure there was something in the papers about him not paying child support a while back and Whyte and Fury have both made reference to his teenage years where it was suggested he was a drug dealer, there is no substance to back this up and may well just be paper talk.
Certainly seems like there is more than meets the eye, he is exceptionally media polished which is the one thing that I cant get on board with, he may just be a genuine angel but I have my doubts.
Either way, whatever he is doing is working so all power to him, I doubt we will see him on holiday buying jagerbombs for the whole bar this summer, but then again Tyson Fury is one of a kind!
