COPENHAGEN, DENMARK - A Swedish court has sentenced a 47-year-old man to seven years' imprisonment for the aggravated sexual abuse of more than 100 under-aged girls via chatrooms, in the largest case of its kind in the Scandinavian country.

The Boras District Court said Friday the man, who was not identified, posed as a young woman or man to contact 114 girls via social media and convinced them to perform explicit sexual acts for him via their webcams.

The court in Boras, east of the southern city of Goteborg, said most victims were aged between 12 and 14, and were abused between late 2010 and mid-2015 when the man was arrested.

The defendant had admitted some of the offences but denied others. It was not immediately clear whether he would appeal.
