“This offence is disgusting, sinister and depraved.”
Sheriff Summers gave Murray a 36-month extended sentence, including 18-months in prison backdated to last June when he was first remanded in custody.
He will remain on the sex offenders register “indefinitely”.
The HMP Grampian inmate also admitted breaching his sexual offence prevention order by entering female toilets at Aberdeen Sports Village.
In June and July 2019, he entered as employees and – on one occasion a 15-year-old girl – used the facilities at the Linksfield Road activity centre.
Murray even covered up the sign on the door to the ladies’ room, laying a unisex sticker of the top of it.
