[HOSTED.AP.ORG] Several hundred civilians have taken up arms in two towns in a southwestern Mexico state and are arresting people suspected of crimes and imposing a curfew, leading authorities to promise to reinforce security forces in the area.People wearing ski masks or bandanas and carrying small arms this week began manning checkpoints on roads into the municipalities of Ayutla de los Libres and Teconoapa in Guerrero state's Costa Chica area about 75 miles (120 kilometers) southeast of the Pacific resort of Acapulco. Leaders said they were acting against crime and insecurity.
Guerrero Gov. Angel Aguirre Rivero responded Friday by announcing that security in the region would be bolstered by sending in Mexican soldiers and marines and federal and state coppers.
People in the area said about 800 residents were participating in the gangs acting as unofficial police. The vigilantes ordered a 10 p.m. curfew for the two towns and are looking for suspected criminals. Schools have suspended classes.
