Authorities arrested an outspoken activist and immigration advocate in southern Mexico on Tuesday, a day before a group of migrants was planning to march to the country's capital to protest their treatment.
According to a federal official, Luis García Villagrán was arrested in Tapachula, in the state of Chiapas, for alleged crimes related to his work with migrants. The official spoke on condition of anonymity because they were not authorized to speak publicly about the case.
