Federal police seized 3.4 kilograms (7.5 pounds) of heroin transported in a hidden compartment of a pickup truck on the Monterrey-Nuevo Laredo highway.
The driver of the pickup truck, with license plates from Texas, was stopped because he was not wearing the seatbelt.
During the inspection the policemen found that a part of the second transmission was altered. The piece was dismantled at the office of the ministerial authorities and four packages of drug were found in it.
The driver will remain under arrest while the investigation continues.
