Authorities in Mexico say they have taken into custody 164 illegal Central American immigrants who were inside a truck that was supposed to be carrying aid to victims of recent flooding in the southern state of Tabasco.

The National Migration Institute says 159 Guatemalans and five Hondurans were hiding in the truck when it was stopped for a routine search.

The driver was arrested.

Many Central American migrants pass through southern Mexico en route to the United States to seek work.
