German law enforcement have confiscated web server belonging to a hacktivist collective called Distributed Denial of Secrets (DDoSecrets) that hosted BlueLeaks, a website that distributed internal documents stolen from US police departments.

On Tuesday, Emma Best, the founder of DDoSecrets has tweeted that prosecutors in the German town of Zwickau seized the organization’s “primary public download server.” Best said that the group are working to obtain additional information, but the seizure appears to be related to the release of the BlueLeaks files.

The move comes several weeks after DDoSecrets leaked a 269 GB data dump containing sensitive data belonging to more than 200 police departments, law enforcement training and support resources and fusion centers. The leaked data included more than one million files, such as scanned documents, videos, emails, audio files, and more.

According to the National Fusion Center Association (NFCA), which investigated the incident, the source of the leak appears to be the data breach at Netsential, a web development company based in Texas, which provides web services to many US law enforcement agencies and fusion centers.

Soon after DDoSecrets published the documents, Twitter banned the organization’s official account for violating social network’s distribution of hacked materials policy.
