Protesters hurl firebombs as Chile leader speaks
The president was not exposed to the violence around the legislature, which is in the port city of Valparaiso.
Authorities said more than 130 people had been arrested and two police motorcycles were burned.
About 10,000 people marched peacefully earlier demanding wide-ranging expansion of free education.
During his speech, Pinera urged legislators not to give into the demands that all education be made free, saying the state shouldn't pay for those who can afford to pay for school.
