Mexico's state-owned oil company says it has found four more illegal taps drilled into pipelines by fuel thieves.
Petroleos Mexicanos says none of the taps caused leaks or spills.
Two of the improvised taps were found in a gasoline pipeline in the northern state of Sinaloa.
Another tap was found in the Gulf coast state of Veracruz. A fourth tap was found in the north-central state of Guanajuato, when police noticed a tanker truck filled with diesel sitting in a field.
Thursday's announcement comes after a Dec. 19 explosion at a pipeline killed 29 people. Pemex officials say that explosion was apparently caused by an illegal tap.
Pemex has suffered more than 614 thefts from pipelines so far this year.
