'Sex-obsessed mum killed two newborn babies so she could go to swingers' club'

Police have arrested a woman on suspicion of killing her two newborn babies so she could visit a swingers' club for sex.

The corpses of the babies were found by 24-year-old Steffie Koppers' father who raised the alarm.

Police believe Koppers, who worked for a local tourism authority, became pregnant with the babies through her sex encounters at the club in Kamp Lintfort, Germany. One of the deaths occurred in November last year.

Bild newspaper reports that the woman was a nymphomaniac who repeatedly bragged about her visits to the sex club Kali on her Facebook page.

In one, she wrote: "I'm in the swingerclub Kali. We are three nice ladies but we want men and there are none here!"

Another read: "It seems it's bad when a solo woman goes to a swinger club to get gratification from more than one man."

Kopper lived on a remote farm with her father at Weeze near Duesseldorf. While she was at work on Tuesday, her father Heinz discovered the baby corpses. One was reduced to a skeleton, the other wrapped in a sheet.

He telephoned the police who arrested his daughter at her place of work.

Murder commission head Gerd Hoppmann said: "She admitted what happened but not comprehensibly able to tell us exactly why."

One cousin told the newspaper: "She was obese. We suspected on more than one occasion that she was pregnant but she denied everything."

Police are now talking to the clientele to of the club try to find the identities of the men who fathered the woman's children.
