Not long ago Chedburn changed a crime enhancer weapon so you can no longer equip it because the item was in 2 categories (Being a weapon & Being a crime enhancer).
I don't fully remember which weapon it was but it was either a "Screwdiver" or "Slim Crowbar"
My guess would be that the person you are mugging has no other weapon equipped other than this one which essentially has been "deactivated" as a weapon so it is glitching out because they have a crime enhancer equipped.
Not 100% sure but Chedburn can have a look.
