EL PASO, Texas -

A convicted sex offender is in custody after being arrested on child pornography charges.

Christopher Peter Swan, 30, has been charged with possessing, receiving and distributing child pornography.

HSI special agents assigned to HSI's Cyber Crimes Group executed a federal search warrant Jan. 8 at Swan's home in northeast El Paso.

According to court records, Swan told HSI special agents he downloaded and possesses a large amount of child pornography and allegedly told them he prefers child pornography that involves 10-year-old children and older.

Swan made his initial appearance Jan. 9 in court, where a U.S. federal magistrate judge ordered him to remain detained pending court proceedings. His detention hearing is set for Jan. 14.

Swan is a registered sex offender who was arrested July 27, 2005 for possessing and distributing child pornography. On Dec. 12, 2006, following his conviction, he was sentenced to 6-and-a-half years in federal prison, which was to be followed by five years of supervised release. He was released from prison in 2012 and has to register as a sex offender for life.
