Man allegedly sexually blackmailed teen

A Canberra man who allegedly threatened to release explicit images of a teenager unless he received sexual favours has been charged with blackmail.

The 18-year-old victim uploaded images of herself to a private online dating site and allowed the 22-year-old alleged offender from Fadden to view them.

He allegedly then contacted her and made threats of blackmail, ACT police says.

She contacted police and a search warrant was executed on the alleged offender's residence and car.

He was arrested, charged and will appear in court next month.

ACT Policing's acting superintendent Jo Cameron said people need to be careful about disseminating explicit images and personal details online because it made them highly vulnerable to exploitation.

"Unfortunately, there are manipulative people in our community who will leverage tools such as online dating sites for their own base needs," she said.
