A Minnesota man has pleaded guilty to answering an online advertisement for baby-sitting work and then using the client's child to make a pornographic video.

Aaron Jay Lemon of Little Canada admitted Wednesday to producing the video in a plea deal with federal prosecutors.

The 23-year-old also admitted to coercing a minor to engage in sexually explicit conduct.

The plea agreement says Lemon filmed the child in St. Paul after seeking the baby-sitting job through Craigslist.

St. Paul police spokesman Peter Panos tells the St. Paul Pioneer Press that the victim was a 2-year-old girl.

The U.S. Attorney's office says the case was part of a project that encourages agencies to investigate the sexual exploitation of children over the Internet.

The office says Lemon potentially faces a maximum of 30 years in prison.
