FORT WAYNE, Ind. (AP): A Fort Wayne man has been charged with child molesting after authorities say he went online to describe illegal sexual activities he’d taken part in with his two young daughters.

The Journal Gazette reports that court records show the 28-year-old man has been charged with several counts of child molesting and other charges.

The man was arrested after he responded to an “advertisement” on a social media app where he described sexual acts he’d performed on his sleeping daughters and sent photographs of his sleeping children in sexually explicit positions.

Police went to the man’s home, where the girls described sexual acts performed by their father. The paper is not naming the man because that would identify his young daughters, the oldest of which is five.
