A 45-year-old man has been indicted on alien smuggling charges, announced U.S. Attorney Jennifer B. Lowery.

A federal grand jury returned the three-count indictment against Hugo Daniel Torres.

On March 2, Torres allegedly attempted to drive an ambulance a Border Patrol checkpoint in Laredo, Texas. The charges further allege authorities became suspicious after the passenger of the vehicle appeared nervous and did not provide proof of citizenship.

At a secondary inspection, law enforcement determined the passenger and one other woman posing as a patient were non-U.S. citizens and were in the United States illegally, according to the charges.

If convicted, Torres faces up to 10 years in prison as well as a possible $250,000 maximum fine.
