A man who posed as Justin Bieber online, has been charged with more than 900 child sex-related crimes in Australia.

A man who posed as Justin Bieber online has been charged with more than 900 child sex-related crimes in Australia.

The man, 42, masqueraded as the singer to solicit explicit
images from children, Queensland Police said.

Already accused of grooming children, the man was this 
week charged with 931 new crimes including three of rape.

Detective Inspector Jon Rouse called the allegations 
"frankly horrendous" and warned young fans of the singer 
and parents to be vigilant.

"The fact that so many children could believe that they
 were communicating with this particular celebrity highlights the need for a serious rethink about the way that we as a society educate our children about online safety," said Mr Rouse.

How the allegations surfaced

Police said the man was already under investigation for
possessing exploitative material and grooming children 
before they searched his computer this week.

They said they had found evidence he had been using "multiple online platforms" including Facebook and Skype
 to communicate with children.

The fresh claims, dating back to 2007, include three 
charges of rape and five of indecently treating a child under 12, police said.

Police did not detail where the children were, but Mr Rouse said the allegations showed "the global reach and skill that child sex offenders have to groom and seduce victims".

He urged parents to help keep children safe online.

The accused man will face a Brisbane court on 6 April.
