Ledger co-founder David Balland and his wife were the victims of a kidnap for ransom plot last week, but they were rescued by French authorities after the kidnappers mutilated one of the crypto executive's fingers.

David Balland and his wife were rescued in a police operation involving elite units, Paris Prosecutor Laure Beccuau said.

According to Le Parisien, David Balland and his wife were kidnapped from their home in Vierzon, France, by a violent criminal gang who subjected them to brutal torture.
