Never heard of him before.
I have never fully understood the concept of "the loveable rogue", when extended to out and out criminals, to be honest. At various times, people like Ronnie Biggs and even the Krays have been described as a loveable rogue. Doubt you would feel that way about them if you had been on the receiving end of their crimes.
I can understand people admiring and supporting a Robin Hood character, and I suppose it might be that some of the law abiding citizens might feel some admiration for those that do not allow themselves to be bounded by the law, but the truth is that there is not much to admire.
It is odd though - various criminals have had a kind of fanbase- that guy who went on the murderous rampage up north, blinding that copper - he had a fanbase, seemingly, for some unfathomable reason, as did that specimen in Manchester who shot the 2 women PCs. And not that long ago we had a judge who described a burglar as "brave".
Cannot understand it myself....
