During the government of general Óscar Humberto Mejía Victores, the Mutual Support Group (GAM) -led by Nineth Montenegro- was founded and the High School Student Coordination Group (CEEM) also gained considerable strength. The latter was formed by students from the Central National Institute for Boys, the Central Normal Institute for Young Ladies Belén and Rafael Aqueche which organized mass protests in September 1985 against the rising prices for public transportation. At least ten people died in Guatemala City in the most extensive wave of urban unrest since protests against the government of Fernando Romeo Lucas Garcia in August 1978. The unrest began with demonstrations against rising prices public transportation but then became widespread due to the bad economic situation the country was in at the time. Burning of buses, blockades and massive protests that resulted in destruction of public infrastructure occurred almost every day. The government responded with three thousand Army soldiers, whom supported by light armored forces and the riot squad of the National Police, were deployed in central and peripheral areas of the city. Also, the night of 3 September 1985 the University of San Carlos of Guatemala was occupied by the military who allegedly found an underground shooting range subversive propaganda.
