A crowd of 500 people were left stunned after a video of a student having sex was played during his school's graduation festivities.

The shocking incident happened during a video presentation at the Gammel Hellerup Gymnasium in Denmark where graduates were being honored.

What started out as a montage of student photos set to music quickly turned into a X-rated shock and awe. The 30-second clip, which witnesses said lasted more like a lifetime, showed the unidentified student having sex with an unknown woman.


"Everyone was shocked – but no-one turned it off. It was clearly too much and the 30 seconds the film lasted, felt a very long time," a student told Politiken, a Danish website.

The video reportedly appeared to be a hidden camera video which may suggest neither the student or the woman knew they were being recorded.

The school's Headmaster Jorgen Rasmussen told The Copenhagen Post that it appears the video was intentionally inserted into the presentation. The students behind the prank have since been identified and punished, Rasmussen said.

As far as the two subjects in the video are involved, school officials are encouraging them to press charges as the pair's privacy was violated.
