Boise detectives helped bust an Illinois man who recently pleaded guilty to child pornography charges, police announced Tuesday.

Andrew Gerald Millas, 43, faces 15 to 30 years in prison when he's sentenced in U.S. District Court in Illinois Jan. 14.

Millas was arrested after Detectives Jason Pietzak and Timothy Brady of the Boise Police Department received child pornography from Millas over the Internet while conducting an undercover investigation on suspected illegal porn websites beginning in December 2011.

Millas described sexual contact with children in online chats with the detectives and broadcasted a live sex act with a minor to them via a web camera. They contacted police in Illinois, who searched the home and arrested Millas.

Millas pleaded guilty Oct. 2.
