MEXICO CITY (AP) — Mexican police and soldiers have freed 81 farm workers from what prosecutors call “inhuman conditions” at a large commercial tomato farm in the northern border state of Coahuila.

Prosecutors say the raid was staged after a complaint was filed against the farm. A total of 68 men and 13 women were allegedly working under unacceptable conditions and forced to spend their wages at a company store.

Such conditions were the kind that sparked the Mexico’s 1910-1917 revolution.

All the farmworkers are apparently Mexicans and they have been put under the care of the national Commission for Attention for Victims.

Prosecutors said late Friday that the ranch was impounded and that the manager and six other people were detained on possible charges of human trafficking.
