Fans of Justin Bieber have been urged to stay vigilant online after a university lecturer was accused of posing as the star to groom children.
Police in Australia have charged Gordon Chalmers, 42, with 931 child sex offenses, including rape, following an investigation, Daily Mail Australia reported.
The law lecturer at Queensland University of Technology in Brisbane pretended to be Bieber, 23, in order to gain explicit sexual images from the children he spoke to, police said.
It is not known how many victims there were, but it's believed he started back in 2007, targeting people all over the world.
Authorities in the USA and Germany gave separate tip-offs to police, leading to his arrest last year.
Chalmers was initially charged in November — leading authorities to obtain warrants to search his computer.
As a result of the search, a large amount of child exploitation material was found, and Chalmers was slapped with hundreds of extra charges.
Totaling 931, they include rape, indecent treatment of children and making child exploitation material, using a carriage service to procure person under 16 and using a carriage service for child pornography material.
He allegedly used online platforms including Facebook and Skype to contact his victims.
Queensland Police have called on Bieber's fans and their parents to ensure they are being safe online.
The Canadian pop phenomenon is currently in Australia on his Purpose World Tour, where he will play in Melbourne this week and Sydney and Brisbane next week.
Detective inspector Jon Rouse said,
Chalmers will appear at Brisbane Magistrates' Court on April 6.
