The drivers did not own the vehicles, but were renting them to work with the service. Only three were registered as current drivers, as one was let go from the company nine months ago for reasons unrelated to trafficking. Another two were fired after being flagged by the National Migration Institute.
"First we saw them on trains, then on buses, then on trucks and today we see them in rented vehicles," Segismundo Doguin, a Coahuila state official at the National Migration Institute, told Reuters.
The Uber caravan picked up the immigrants in Matehuala, with each rider paying 3,000 pesos ($162) to be driven 342 miles to Reynosa, along the Texas border.
Uber has issued a statement denying any responsibility for the drivers.
"The company does not own the cars registered on the platform, nor does it employ the drivers, who are independent contractors," Uber said.
It appears to be a growing trend. Just months ago, another large caravan was caught doing the same thing.
"About two months ago, seven other vehicles were detected in the area of San Luis Potosi state… and were also in the Uber system," Doguin said.
