Mexican authorities say they have arrested three members of the Zetas drug cartel who later confessed to the June slaying of bodyguards for the governor of the northern state of Nuevo Leon.
A federal prosecutor's aide says the men were captured during a traffic stop Saturday.
The aide spoke on condition of anonymity due to safety concerns.
The aide says the men confessed to killing two of Gov. Rodrigo Medina's guards in June; a guard for a town mayor last year, and three police officers in May.
The suspects were identified as 24-year-old Arturo Garcia Celaya, 25-year-old Jose Daniel Hernandez Guzman, and 34-year-old Nicolas Yepes Alvarez.
The aide says Garcia and Hernandez were fugitives following a prison escape last December.
