A woman in Sweden has been charged with engaging in sexual activities with a human skeleton and could face jail time for disturbing the peace of the dead, a Swedish prosecutor said.

Police found a full human skeleton, skulls and a box containing other human bones by chance after responding to a call saying a shot had been fired from her flat in the city of Gothenburg.

They also discovered CD-ROMs titled "my necrophilia" and "my first experience", and photographs of the woman engaging in various sexual activities with a skeleton, a court document on the prosecutor's website showed.

It said the woman had handled the bones in a "shameful" and "unethical" manner.

"She is interested in the dead," Prosecutor Kristina Ehrenborg-Staffas told Reuters. "She has pictures of morgues, churches and graveyards."

The 37-year-old unemployed woman has also been accused of selling human bones to an artist in Uppsala in eastern Sweden this past summer.
