Valencia police arrested six people on Friday after security forces reportedly charged a group of students who had gathered near a police station to protest the arrests of 10 people in another demonstration the previous day.

Riot police armed with shields and clubs surrounded the students — many of them juveniles — who had gone to the Zapadores headquarters to demand that police release those who were arrested for protesting social service cuts by the regional government. Some parents said they will file charges against the police for illegally detaining some of their children.
