Austrian investigators in April discovered Josef Fritzl fathered seven children with his daughter, Elizabeth, while he kept her in a sound-proof, windowless room for 24 years.

Family lawyer Christoph Herbst said Tuesday he filed multiple lawsuits against various media publications that revealed private conversations with Elizabeth and pictures of her children, The Daily Telegraph said.

Austrian legal experts said the media violated her right to privacy. Herbst said he will expose Elisabeth to the media coverage so she understands the legal proceedings.
