What started out as two people volunteering at the same premises soon became something sinister.
Alex Stryfe, 35, appeared before Judge Garry Barkle in Whanganui District Court on Monday to be sentenced on seven charges of exposing a young person to indecent material and one charge of meeting a young person following sexual grooming.
Judge Barkle sentenced Stryfe to 16 months and two weeks imprisonment on all charges.
"You met the 15-year-old victim while you were both volunteering at the same premises," Judge Barkle addressed the defendant.
"Within a short timeframe, you started communicating with her via Facebook Messenger. The messages started out innocent and developed into messages with sexual overtones."
