Women are being urged to come forward to police if they think they have been exploited on a recently shut down Facebook page.
The Dunedin-focussed "Rack Appreciation Society" page which included explicit pictures of female University of Otago students without their permission was shut down following complaints to Rape Crisis and the university.
If any woman's image had been stolen or placed on the site, or had been taken without their consent, they were encouraged to make contact with police, said relieving Area Commander Inspector Mel Aitken.
"Each case would be assessed on an individual basis to ascertain whether an offence had occurred.
"These kinds of sites are not necessarily unlawful but we do appreciate that they can cause significant upset and social harm."
