The Mossos d'Esquadra, Catalonia's police force, as well as Spain's National Police Corps and Civil Guard have referred this week's road blocks around Catalonia to prosecutors at the National Audience. Similarly, the frustrated block yesterday to an AVE high-speed train line near Bàscara where one of the cars identified belongs to a daughter of Catalan president Quim Torra in which were travelling a man and a woman.

There is already a terrorism investigation open against the protest platform Tsunami Democràtic for their action at Barcelona airport on 14th October. Last month, the case led to an order to shut the group's website.

The different forces have passed over all their reports from this week to the public prosecution service. Not included, however, is the blocking of the border with France. That action was, on purpose, kept to the French side of the frontier, meaning it doesn't fall under the jurisdiction of Spain.

The investigation

The three Spanish forces have been working together on the police response to the protests in Catalonia from a coordination centre since the Supreme Court published its verdicts on 14th October.

Four days later, the National Audience started an investigation into Tsunami for terrorism. Judge Manuel García-Castellón ordered its web site to be shut; the platform responded by opening a backup page on a server abroad. The case is not focused so much on the protests themselves as on the organisation behind them.
