Austin Jones was charged with two counts of production of child pornography, according to a complaint filed on Tuesday in U.S. District Court in Chicago, where he appeared. He is being held in federal custody pending another hearing on Thursday.

Jones has racked up millions of views on YouTube, a unit of Alphabet, with his covers of pop songs and has more than 200,000 followers across his Twitter, Instagram and YouTube channels.

Jones’ attorney Gerardo Solon Gutierrez said by phone that the singer was “innocent until proven guilty.”

His arrest marked another scandal involving YouTube’s social media personalities. In February, YouTube and Walt Disney cut ties with influential Swedish social media star PewDiePie, who boasted some 53 million YouTube followers, after he posted a series of videos deemed anti-Semitic.

According to the federal complaint, Jones used Facebook and Apple Inc’s iMessage service to request sexually explicit videos from girls aged about 14 to 15.

The documents allege that Jones sent numerous messages to two 14-year-old female fans from 2016 and 2017 in which he instructed them to expose their genitals in videos sent to him through Facebook.

A review of his social media activities showed that “his primary fan base appears to be teenage girls,” the court documents said, adding that Facebook shut down Jones’ page a month ago due to his involvement with minors on the network.

Facebook Inc said in a statement on Wednesday: “We have zero tolerance for sharing or soliciting child exploitative images or videos on Facebook, and we cooperate with law enforcement agencies that investigate these crimes.”

Representatives for YouTube and Apple did not immediately respond to requests for comment.
