After the SEK operation on Thursday morning because of possible rampage plans in Leipzig, the police gave the all-clear. The video, which a man uploaded to the Snapchat social network and which attracted attention as a possible rampage announcement, was created as part of a school project, according to the police.

There was no danger, said the Leipzig police department. The police had been warned by American authorities that the 21-year-old had uploaded a video to the social network Snapchat that indicated a possible act of violence at a school.

Forces of the special task force and the Leipzig police department then stormed the apartment of the 21-year-old. The man was initially arrested but has since been released.

The investigations have now revealed that the video showed part of a project at a Leipzig school that was carried out without a teacher. It showed, among other things, a person with a gun in his hand in a classroom.
