Mexican military officials said they rescued 189 undocumented immigrants from a Reynosa stash house during a Sunday night raid.
An anonymous tip reportedly led authorities to a home off Calles Doctor Plata and Rio Purificacion in the Colonia Doctores.
Mexico's El Universal newspaper reported that officials found 157 men and 32 women inside the house around 11 p.m. Sunday.
The newspaper said the immigrants were all from Brazil and Central America.
Many of the immigrants told investigators reported that had paid as much of $1,500 to be smuggled into the United States.
El Universal reported that it took some of the immigrants as long as three months to reach Reynosa from their home countries.
