Wagner Group [1] is a mercenary company, by the way, named after German composer Richard Wagner [1]. Russian businessman Yevgeny Prigozhin [2] is reportedly the founder and owner.
(Wagner is not a person. Or am I misreading: who does "himself" refer to?)
Ah yes, that is wrong, but I think people who are into russian geopolitics (like me) autocorrected it and had the meaning of the person arrested automatically transfered to Prigoshin as head of Wagner.
>He is alleged to have founded the Wagner Group, with his own call-sign reportedly being Wagner
