A Dane studying at the prestigious Yale University is facing criminal charges, including voyeurism, for allegedly showing his four roommates a video of himself and his then-girlfriend having sex.

Casper Desfeux, native of Copenhagen, Denmark, told police he recorded the incident without the woman's knowledge using a camera on his Apple MacBook, according to the arrest warrant affidavit.

The woman, also a Yale student, found out about the video from one of Desfeux's roommates, according to police.

Desfeux, 20, a second year student, told police he activated the camera because he just "wanted to see if it worked."

Police say the woman brought the charges to prevent the sexually explicit video footage from being disseminated around the university or on the Internet.

Desfeux was arraigned Thursday in Superior Court on voyeurism and dissemination of voyeuristic materials, officials said.

A telephone message was left Thursday for his attorney.

Desfeux told Yale police he never sent the video to anyone because, at 45 minutes, it was too lengthy to process. He also said he did not make any still photos from it, the New Haven Register reported.

Police have seized the laptop, camera and other items, which are being held in the evidence room of the Yale Police Department until they can be delivered to the state police forensic laboratory for examination, according to the affidavit.
