Mexico City (CNN) Jesus Alfredo Guzman, the 29-year-old son of jailed Mexican drug lord Joaquin "El Chapo" Guzman, has been freed after he was kidnapped a week ago in Puerto Vallarta, three sources confirmed to CNN.

A high-ranking source inside the Mexican government confirmed he was freed, and a source close to the Guzman family said El Chapo's son, who was kidnapped along with five other people by seven armed men, is now in Sinaloa, Mexico.

Journalist Anabel Hernandez confirmed to CNN that according to sources inside the Guzman family, El Chapo's son was freed on Saturday.
