The pair, aged 17 and 16 at the time of the incident, first made contact with the man on an internet chat site.

After paying numerous visits to his home it is reported that they agreed during a particular meeting to indulge in a sex game.

The man was tied naked to a chair with his mouth taped yet once securely fastened the teenagers decided to change the rules. During police questioning the man said one of the girls “got a knife and threatened him directly with it.”

It was during this time the girl forced the man to reveal the pincode of his bank card.

“She told me it was in my best interest to give her the correct pincode otherwise there would be consequences,” the man told police.

The girl’s account reveals that she had previously asked the man if he was willing to pay for sexual services and be tied up. He agreed to her request and,”said among other things that he wanted to have a carrot inserted in his anus.”

The women finally left the apartment taking the man’s laptop, mobile phone and various other valuables with them. The man, however, was left in shock, still tied up naked to the chair.

He was eventually able to free himself and raise the alarm to the police.

A 19-year old woman, also accused, was waiting outside the man’s home and accompanied the pair to a cash machine where they took money from the man’s account. She was acquitted, however, entirely of all criminal charges.

The three teenagers are already known to police for activities including assault, theft, and shoplifting.

The eldest, now 18 was handed a probationary sentence while the younger girl, now 17, was sentenced to juvenile care.
