A man who impersonated pop icon Justin Bieber online was arrested in Australia on Thursday on charges of 931 child sex offenses, reported CNN.
Bieber, a 23-year-old Canadian with more than 92 million followers on social network Twitter, ranked among Forbes' most powerful celebrities from 2011 to 2013, is visiting Australia on his Purpose World Tour.
Gordon Douglas Chalmers, 42, a resident of Queensland, was detained in November on suspicion of pedophilia after authorities in Germany and the United States alerted the Australian authorities, Efe news reported.
The man is accused of using Facebook, Skype, and other online platforms to communicate with his victims.
A lot of child exploitation material was found on his computer, they added.
"Detectives had been investigating a man who allegedly posed as Justin online in order to solicit explicit images from young children", said the police, according to AFP.
He was also charged with possessing child porn.
He was charged with extortion, manufacturing child pornography and communicating with a minor with the intent to commit a sex act in California.
Hence, the police warned parents and Bieber fans to be extra vigilant when using the internet.
Police have not said how many children are alleged victims or in what countries they live.
The new charges include indecent treatment of children and making child exploitation material.
Detective Inspector Jon Rouse said the allegations "highlight the need for a serious rethink about the way that we as a society educate our children about online safety".
"The breadth of offenses committed in this instance are frankly horrendous and I want to recognize the efforts and commitment of the investigative team at Taskforce Argos to keeping children safe".
