42-year-old man who posed as Justin Bieber online charged with 900 child sex offences in Australia

A man posing online as pop superstar Justin Bieber was Thursday charged with more than 900 child sex offences in Australia after enticing young fans to send him explicit images, police said.
Gordon Douglas Chalmers, a 42-year-old law lecturer at the Queensland University of Technology in Brisbane, was charged in November with using Facebook and Skype to impersonate the star after tip-offs from US and German authorities.
A police statement said Chalmers was charged this week with another 931 child sex offences dating back a decade including rape and making child exploitation material.
Chalmers has not entered pleas.
“Detectives had been investigating a man who allegedly posed as Justin online in order to solicit explicit images from young children,” Queensland state police said in a statement.
“As part of the investigation, a 42-year-old man had earlier been charged with a number of child sex offences including possessing child exploitation material and using a carriage service to groom persons under 16.
