Detective Chief Inspector Steve Williams, senior investigating officer for North Wales Police, said:
I would like to pay tribute to the courage of the victim in this case, who has shown a great deal of resilience and strength in very difficult circumstances.
I sincerely hope that the guilty verdict will provide some closure on this horrendous ordeal for the victim and that she will be able to rebuild her life which was shattered by the events of May 30th 2011.
No-one is above the law and I welcome the conviction which again demonstrates that North Wales Police, in conjunction with our partners at the Crown Prosecution Service, are absolutely committed to investigating all incidents of this nature fairly, professionally and robustly to ensure that those responsible are brought to justice.
