CHAMPAIGN, Illinois – University of Illinois Police arrested a 32-year-old Champaign man who had dozens of sexually-explicit videos of children saved to his cloud storage account.

Juntian Tong, who resides in the 200 block of East John Street, Champaign, was arrested for possession of child pornography Thursday after detectives served a search warrant at his apartment. “Child pornography” is a legal term that refers to child sexual assault material.

Thursday’s arrest resulted from an investigation that began with a tip from Google in January, when the computing giant told the National Center for Missing and Exploited Children that they had detected two videos with a digital signature that matched known child sexual assault material. The videos were being stored in a cloud account.

The tip was passed on to law enforcement through the Internet Crimes Against Children (ICAC) task force, a national network of investigators with branches in most states. The University of Illinois Police Department has two detectives who have membership in the Illinois branch of ICAC. Those two are specially trained to investigate crimes involving child sexual assault material.

After collecting more digital information associated with the crime tip from Google, investigators obtained a search warrant for Tong’s online accounts. They found 53 videos depicting minors in a sexual manner.

Based on this evidence, investigators obtained a search warrant for Tong’s apartment, where he was arrested on Thursday. He was taken to the Champaign County Jail.

The University of Illinois Police Department has made several arrests for possession of child pornography in recent years because of its partnership with ICAC.

Please note, those arrested are presumed innocent until proved guilty, and formal charges may change as cases are adjudicated.
