A man considered “one of the main leaders of the criminal organization led by Edgar ‘La Barbie’ Valdez Villarreal in Morelos state” has been arrested by the Federal Police, the Mexican Public Safety Secretariat said.

Nelson Horacio Vargas Garcia was arrested on Dec. 8 near Ticuman, a town outside the city of Tlaltizapan, the secretariat said.

The 34-year-old Vargas Garcia ran the operations of the gang led by Valdez Villarreal, who was arrested by the Federal Police on Aug. 30, 2010.

Valdez Villarreal, who was born on Aug. 11, 1973, in Laredo, Texas, was a high-level member of the Beltran Leyva cartel and got his nickname because of his fair skin and blue eyes.
