BUDA, Texas (KXAN) – A traffic stop for a dirty license plate led Buda police to two human smuggling suspects.

The officers stopped a pickup truck last month on Interstate Highway 35  because it had a mud-covered plate. They found three people concealed in the car.

Officers arrested Fermin Rubio, 18, and Robert Trevino, 19, both from Carrizo Springs. They are charged with human trafficking, a second-degree felony. Both men were released on $10,000 bond each.

The men who were hiding told police they paid $100 to Rubio for a ride.

Police said the pair was taking illegal immigrants from a home near the Mexican border to safe house in Dallas.
