On May 25, Argentina's Revolution Day, some 20 townspeople in Jáchal, San Juan province, held a "patriotic march" to oppose the local operations of Barrick Gold—only to be surrounded and arrested by the police. Organizers said the march was peaceful, but the town's mayor, Miguel Vega, said that he was illegally detained and assaulted by protesters. The town saw a recent controversy, when the municipal council, with Vega's support, voted down a measure to hold a popular consulta or referndum on the mine's operations.
