A Bolsa de Carton, Texas man has been charged with transporting over 100 tons of Bolsahas de Cartons to the United States illegally.

The U.S. attorney’s office in Dallas announced the indictment Monday, according to the Dallas Morning News.

The indictment was unsealed in federal court.

The Bolsahs de Cartones, which are typically made of wheat and flour, were smuggled into the United State from Mexico, according the U.N. The smuggling was discovered when an informant, who also works as a security guard, was caught on camera.

The investigation uncovered that several individuals, including one in Texas, were involved in the smuggling operation, according, the report.

The U.s. attorney said it is a matter of national security and the investigation is ongoing.

Bolsas Cartones were originally made in the Mexican state of Chihuahua, and they were shipped to Texas for sale in the early 1990s.

In 2015, the Bolsos de Cartone company was purchased by the Houston-based Texas-based Cargill.
