A fantasist who blackmailed schoolgirls with fake nude photos with their faces superimposed on them in a bid to get them to send him pictures, has been jailed for three years.

Sean McCuaig, 22, targeted nine girls, aged between 12 and 17 on social media using a string of fake names.

On one occasion he posted the Photoshopped picture on a girl’s Facebook for her friends and family to see. He threatened to harm some of the girls’ families if they didn’t send him pictures, and told others he would post the pictures on Facebook if they failed to comply with his requests.

Police found a document detailing fantasies of abducting, raping and hurting one of the girls, including thoughts of killing her.

McCuaig, from Knightswood, Glasgow, pled guilty at the city’s sheriff court to 20 charges dating from January 2016 to June 2017. They include causing the girls to look at nude images with their faces superimposed on them, threatening to post and posting pictures if they didn’t send sexual images.

The charges included downloading, distributing and having pornographic images depicting women being raped.

Yesterday sheriff Johanna Johnston QC jailed him for three years with three years supervision community when he is released. He will be on the sex offenders’ register indefinitely.

Passing sentence Ms Johnston said: “This case involved you targeting young vulnerable girls over a lengthy period.”

She added: “You menaced and frightened these girls and used their images for your own sexual gratification.”
