Javier Gómez Bermúdez is a judge of Audiencia Nacional, a special high court in Spain that deals with serious crimes such as terrorism and genocide. According to press reports, he ordered arrest warrants that were carried out on December 16th against alleged members of an anarchist group. The arrests were part of Operation Pandora, a coordinated campaign against "anarchist activity" that has been called an attempt  "to criminalize anarchist social movements." The police seized books, cell phones, and computers, and arrested 11 activists. Few details are known about the situation, since the judge has declared the case secret.

At least one lawmaker, David Companyon, has speculated that the raids are a "stunt to garner support for Spain's recently approved 'gag law.'" The new law severely restricts demonstrations, setting huge fines for activities such as insulting police officers (€600), burning a national flag (up to €30,000), or demonstrating outside parliament buildings or key installations (up to €600,000). Considering the provisions of the law, it's no surprise that many see the raid, conducted against a group with political ideas that the government appears to find threatening, as connected.

In a statement, Riseup noted:

Four of the detainees have been released, but seven have been jailed pending trial. The reasons given by the judge for their continued detention include the possession of certain books, "the production of publications and forms of communication", and the fact that the defendants "used emails with extreme security measures, such as the RISE UP server.
