Mexican police arrested 49 undocumented Guatemalan migrants in the southern border state of Chiapas, authorities said.
The travelers were detained after a routine inspection at a checkpoint in Arriaga determined that the 44 men and five women were carrying forged documents.
The migrants were traveling in a bus without license plates.
Five people accompanying the migrants were arrested on suspicion of human trafficking and the Guatemalans were taken to the border town of Tapachula for repatriation.
Large numbers of Central Americans undertake the hazardous journey across Mexico each year on their way to the United States, although the number of border crossers fell from an estimated 433,000 in 2005 to 140,000 in 2010 due to recent U.S. economic woes.
The trek is a dangerous one, with criminals and corrupt Mexican officials preying on the migrants.
