A total of nine clandestine oil taps were found in different points in the areas of Altamira and Ciudad Madero in southern Tamaulipas. Federal Police carrying out surveillance work along the Madero-Cadereyta pipeline were alerted to the presence of armed people guarding a pipe near a vehicle parked on the side of the Tampico-Mante highway (El Financiero). The CNS confirmed the seizure of six vehicles, including several trucks with drums for holding fuel (La Jornada). In the first eight months of 2016, Tamaulipas has recorded 547 instances of illegal oil tapping, third among Mexican states, behind Puebla and Guanajuato (El Financiero).
