An online predator posed as US pop sensation Justin Bieber to sexually prey on a 10-year-old girl.
The Sydney girl sent a friend request on an Internet video-chat program last Monday to a person using a profile that included Bieber's photograph and personal details.
In subsequent online video conversations, the girl was asked to model revealing clothing.
She told her mother about it, who then reported the matter to the police.
"This incident serves as an important reminder that online predators will stop at nothing to groom children," News.com.au quoted State Crime Command's Sex Crimes Squad commander Detective Superintendent John Kerlatec, as saying.
"We advise parents to educate their children about these dangers, and to warn them to be wary of anyone who claims to be famous," he said.
