Agents conducted a “worksite enforcement action” at Abby’s Bakery in Los Fresnos and apprehended eight immigrant workers on Feb. 12 following a tip the agency received in December, according to Special Agent Dillon Duke with Homeland Security Investigations, who testified during a preliminary hearing Friday morning.

Six of the immigrants were in the country on temporary visas that do not grant them permission to work in the U.S. It is unclear if they were in the U.S. longer than their visas permitted, but immigration officials have since removed them to Mexico.

The tipster informed the agency that the business owners were harboring and employing immigrants without pay, Duke said. However, when the agents questioned an employee, he said he received $8 per hour.

During the raid of the business — whichalso includes Dulce’s Cafe — agents also searched an apartment located on the side of the building where several of the employees lived. Duke described the apartment as a rectangular room with six beds along the wall, two bathrooms and no kitchen. The windows were covered with cardboard.

Agents also questioned the couple, who allegedly admitted they knew their employees were not authorized to work in the U.S.
