A Santa Clarita man was arrested Friday by federal authorities in connection with a series of child sexual exploitation cases.

Ian Nathanial Johnson, 36, of Santa Clarita, was arrested Friday after prosecutors filed a criminal complaint charging him with distributing and possessing child pornography.

The investigation into Johnson was launched after the National Center for Missing and Exploited Children received information that Johnson had uploaded Child Sexual Abuse Material (CSAM) to a Dropbox account, according to the complaint affidavit.

“Pursuant to a search warrant, agents seized Johnson’s digital devices and discovered over 200 images of child pornography and chats on Telegram, several of which included images of prepubescent children and children in bondage,” the affidavit states.

Johnson is scheduled to make his initial appearance on Wednesday in the United States District Court.

Homeland Security Investigations (HSI) is conducting the investigation into Johnson.

“HSI Los Angeles is committed to removing sexual predators from our streets and working aggressively to hold them accountable for their heinous actions,” said HSI Acting Special Agent in Charge Wang.

Johnson is one of nine cases announced by the Department of Justice on Tuesday, and is part of Project Safe Childhood, which is the Justice Department’s longstanding initiative to combat the ongoing epidemic of child exploitation crimes.

Assistant United States Attorney Catharine Richmond from the Violent and Organized Crime Section is prosecuting this case.
