The man was sentenced by Uppsala district court for a list of 65 charges of sexual offences including aggravated child exploitation through sexual posing, child rape, and sexual coercion.
The 33-year-old father of two was also ordered to pay a total of 1 million kronor ($140,400) in compensation to the girls.
The court found the man guilty of the charges in the beginning of July but his sentencing has been delayed due to him undergoing a month’s psychiatric examination.
The examination has led to the conclusion that the man is not suffering from any serious psychological impairment.
The case came to light after the man was accused of raping a 14-year-old girl from the Stockholm area who he had known previously, rather than through an encounter on the internet.
A girl from western Sweden contacted police shortly thereafter to report that a man had contacted her on the internet and forced her to perform sex acts in front of a webcam and threatening to kill her if she did not comply.
Police were then able to trace the man’s IP-address and discover that the accused rapist and the webcam offender were the same man.
The 33-year-old was arrested in December 2008 and was charged by the Uppsala court at the end of May. He has remained in custody throughout the duration of the investigation.
