Zürich University has provoked the anger of students after it emerged that it had installed security cameras in one of its men's toilets. 

The camera was installed to combat repeated vandalism of the toilets by graffiti artists. But according to newspaper 20 Minutes, the presence of the camera angered one student so much that he removed the camera from the ceiling and complained to university bosses.

University spokesman Beat Müller, while insisting that the camera was pointed at the door and only filmed people entering and leaving, said the incident was "unacceptable and regrettable".

Local data protection officials told the newspaper that only police were authorized to install surveillance cameras, but that the university had a right to use technology to combat vandalism.

The university added that the camera had successfully identified a graffiti artist believed to be responsible for the vandalism in the toilet.
