Author and comics writer Gerard Jones, perhaps best known for his acclaimed 2004 book "Men of Tomorrow," was arrested last week on suspicion of possessing and distributing child pornography.

According to SFGate, the 59-year-old writer was arrested Dec. 29 following a police investigation and search of his San Francisco home allegedly uncovered electronic devices storing more than 600 images and videos depicting child pornography.

Authorities say Jones uploaded videos to YouTube depicting a child performing sexual acts on an adult, while a video allegedly found in his home is said to show children as young as 1 year old. KTVU adds that investigators believe Jones also traveled to London several years ago to have sex with a minor.

He pleaded not guilty Thursday to charges of possession of child pornography and distributing child pornography. His attorney stated that Jones, who has no criminal record, denies the accusations.

Jones worked for more than a decade as a comic writer, co-creating "Prime" and "The Trouble with Girls" at Malibu, and "El Diablo" at DC Comics, and penning such titles as "Green Lantern," "Justice League" and "Hulk 2099." However, he's become better known for his Eisner Award-winning book on comics history, "Men of Tomorrow: Geeks, Gangsters, and the Birth of the Comic Book," and on violent entertainment, "Killing Monsters: Why Children Need Fantasy, Super Heroes, and Make-Believe Violence."
