On 22 April 2017, the web site MagaNews.co published an "article" that was nothing more than a photograph and clickbait headline, claiming that Chelsea Clinton had been arrested for having sex with a minor:

MagaNews provided no information about the alleged arrest (such as where and when it occurred or which agencies were involved) and we found no genuine news reports confirming the article's claim.
Furthermore, Clinton has made at least one public appearance since her alleged arrest — she attended a student art show in El Paso, Texas — and has been active on social media. Here's a photograph of Clinton at the student art show on 23 April 2017, the day after the MagaNews.co article was published:
Thank you Chloe for making the lovely flowers from toilet paper rolls & giving me Sprinkles, the green bird you made! pic.twitter.com/E0w2a6RTUd
