An Alabama man has been indicted on child porn and extortion charges after authorities say he posed as pop sensation Justin Bieber online and convinced young girls to send him inappropriate photos.

The Thursday indictment alleges that Christopher Patrick Gunn of Montgomery would also pose as a new kid in town on social media sites. Court documents state that Gunn would promise girls between ages 9 to 16 Bieber concert tickets or otherwise extort them to provide sexually explicit photos and videos.

Gunn has been charged with two counts of producing child pornography, three counts of interstate extortion and three counts of using a computer or cellphone or illegal activity.

The indictment identifies victims in Louisiana, Alabama and Tennessee.

It is not immediately clear if Gunn has an attorney.
