Not very surprising. He had already been arrested, back in 2002, for selling illegal stuff on eBay. He was somewhat of an attacker of Bitcoin, promoting his "bcash" fork.
For reference, that "illegal stuff" were just fireworks (too powerful, I guess) [0]. Those "attacks" are fully explained in his recent book "Hijacking Bitcoin: The Hidden History of BTC" [1]. He didn't fork Bitcoin, he just proposed its name: Bitcoin Cash [2], which is not "bcash" [2][3].
