Los Angeles - A California man was arrested after authorities say he emailed explicit images of a three-month-old boy to England.
Robert Schrader, of Littlerock, was arrested on Monday and remains jailed on federal charges of producing child pornography.
Prosecutors say British authorities alerted a US diplomat last month that someone had sent the images to an undercover investigator.
Authorities say data embedded in the images showed they were taken in the area of Schrader's home.
A Homeland Security official says the baby is one of the youngest child pornography victims ever identified in the Los Angeles area, if not the youngest.
