Federal agents descended on a tortilla factory Tuesday morning in the Heights.

The raid began about 10 a.m. at La Espiga de Oro at 1200 15th Street near Shepherd, said Gregory Palmore, a spokesman for Immigration and Customs Enforcement.

Palmore said agents with Homeland Security and the Department of Labor served a criminal search warrant at the business. He said he could not reveal details about the case because the investigation is ongoing.

Eleven workers from the factory were detained at the scene, Palmore said. He said they are expected to be questioned.

No other information was available.
