A sick predator thought to have targeted thousands of children online was finally snared after a report from a brave Scots girl. Alexander McCartney, dubbed the 'world's worst catfish', was jailed for life this week for his vile crimes.

The beast, 26, admitted 185 charges involving 70 children, although a court has previously been told that the real number of victims is much higher. His evil actions led to a young girl and her father taking their own lives.

McCartney, from Northern Ireland, posed as a young girl to befriend other girls on Snapchat. He would blackmail his victims after they shared intimate images, threatening them with their families and online.

In 2019, a 13-year-old Scottish girl was being targeted by the paedo and bravely called cops to report him. Police Scotland contacted the Police Service of Northern Ireland (PSNI) and he was subsequently arrested.

Following his arrest, an investigation into the 'horrific' case has revealed victims from across the globe, including 12-year-old Cimarron Thomas. The schoolgirl from West Virginia in the US took her own life in May 2018, after McCartney demanded she involve her younger sister in sex acts.

Eighteen months later, her distraught father Ben Thomas also died by suicide. McCartney has pleaded guilty to manslaughter relating to Cimarron’s death. This week, he was jailed for life at Belfast Crown Court with a minimum term of 20 years.

As reported in the Mirror, his global web of catfishing, blackmail and sexual abuse is believed by police to have targeted about 3,500 children. The “terrified and distraught” child pleaded with McCartney to leave her alone but he told her he would start “spreading” the photos unless she gave him what he wanted. She messaged him saying “I will shoot myself…”

McCartney callously replied “Goodbye and good luck.” Following the end of their chat Cimarron’s younger sister found her sibling dead on the floor of their parent’s bedroom with a gunshot wound to the head and her father’s handgun nearby, the court heard.

He also admitted 59 counts of blackmail, dozens of charges related to making and distributing indecent photographs and scores of charges of inciting children to engage in sexual activity. the offences took place between 2014 and 2019, with victims linked to Australia, New Zealand and the US.

The scale of the offending by McCartney shocked even the most experienced investigators, one describing it as a “paedophile enterprise”. McCartney, who carried out the crimes from the bedroom of his childhood home, used his technical knowledge as a computer science student to carry out his crimes.

He posed on the Snapchat social media platform as a teenage girl and befriended vulnerable girls aged between 10 and 16 who were gay or exploring their sexuality. Once he had secured a picture from his victims, he would then reveal the “catfish” and blackmail them into taking part in sex acts.

In some cases, he demanded his victims involve younger siblings. McCartney told one girl he would get people to go to her house to rape her if she did not comply with his demands.

When police raided his home in March 2019, he was in the middle of offending and Snapchat was open on one of his phones. Devices seized from his bedroom were found to contain hundreds of thousands of indecent photographs and videos of underage girls.

At a pre-sentence hearing last week, a prosecuting barrister said McCartney had degraded and humiliated his victims, stating that the harm caused to them was “unquantifiable”.

The barrister also read out parts of a victim impact statement, which had been provided to the court by the grandparents of Cimarron Thomas. The statement said: “Our lives will never be the same. We didn’t get to see her graduate, walk down the aisle or have children. We have been robbed of those memories. Our lives have changed forever.”
