Chilean military police (carabineros) violently attacked again freedom of expression and protest in Santiago. The student demonstration was scheduled to march to the Heroes Plaza after marching through the Alameda, the city's main street, but was brutally repressed (again) by the police-soldiers, who arrested 600.
The government had explicitly forbidden the march through the Alameda in a clear attempt to hide the student protests that are the major challenge that the extremist right-winger President Piñera faces. All previous demonstrations have used this major street as avenue to show their discontent.
