The 21-year-old ex-phone owner was out at a bar in Sundsvall, northern Sweden, on Saturday evening when she discovered her phone had been stolen, according to Sundsvall Dagbladet newspaper.
Her mobile telephone was in the back pocket of her trousers, which made easy pickings for the thief's light fingers.
The thief took the opportunity to pilfer the phone, but wasn't finished there.
Upon discovering that the woman had an unlocked phone with no password, the burglar took the pleasure of scrolling through the 21-year-old's private pictures, which included several naked images of the woman.
Taking the snooping one step further, the telephone-taker discovered that the woman's personal Facebook page could also be signed into without a password.
It all proved too tempting for the thief, who proceeded to upload the woman's naked pictures onto her own Facebook site.
The woman was made aware of the incident and managed to remove the pictures, yet it remains unknown if the images spread further, according to B-O Hägglund of the Sundsvall police.
The police have labelled the crime as theft and sexual harassment; however the thief is still unidentified and remains at large.
