Scuffles broke out between police and students protesting in the underground station of Plaza de Catalunya in Barcelona on Thursday, during a general strike in protest of the trial of Catalan political leaders.
Riot police tried to chase away students who occupied the underground rail tracks and chanted slogans for Catalan political prisoners.
Footage shows students forcing police officers out of the subway, while police officers responded by chasing and hitting protesters with batons outside the station.
