U.S. Immigration and Customs Enforcement agents appear to have detained workers at the Tres Dimensiones Ropa Usada on Thursday morning. 

ICE agents arrived at the facility, located at 7901 S. 23rd St. in McAllen, about 10 a.m., according to eye witnesses. 

Some employees were put on a bus as families of the detained, along with members of La Union Del Pueblo Entero and other onlookers gathered outside. They were still present as of 3 p.m.

Texas Department of Public Safety troopers stood guard as ICE carried out enforcement efforts inside.
