Former Mexican attorney general Jorge Carpizo is suing journalist Anabel Hernandez and Random House Mondadori, which published her book The Drug Lords, the Knight Center for Journalism in the Americas reported.

In The Drug Lords, Hernandez claimed that  Carpizo walked away with part of the $400,000 reward offered for the arrest of ‘El Chapo,'” a drug trafficker, according to the Knight Center.  Carpizo “is responsible for the arrest” of El Chapo.

According to Mexican daily newspaper Milenio, Carpizo claims Hernandez’s book libeled him.
