A riot police officer chases teacher trainee protesters as other protesters take cover behind chairs during clashes at the Parque de la Industria in Guatemala City July 2, 2012. Riot police and teacher trainees protesting against a proposed two year increment to the teacher training program clashed on Monday after the trainees briefly detained Guatemala's Education Minister Cynthia del Aguila during an event at the Parque de la Industria, according to the government. Del Aguila was later rescued by riot police and received treatment for exposure to tear gas.
