Well, this is just about as disturbing as it gets.
A 34-year old man named Lee Moir has been arrested in New Jersey on charges of extortion, manufacturing child pornography and luring, according to a statement by acting Essex County Prosecutor Carolyn A. Murray.
Moir allegedly impersonated Justin Bieber online in order to attract the attention of an unidentified 12-year old girl. She tried to cut off contact once she learned the truth, but Moir is then accused of threatening the victim's family and forcing her to perform Web cam sex acts.
Moir hails from Toronto and authorities say he has been in contact - via Facebook and other social media accounts - with "many juvenile females" in the United States, Canada, France, Australia and the Philippines.
He was brought to justice this month when he solicited an undercover police officer posing as a 14-year old girl and was arrested at the location where he agreed to meet her.
