An NSPCC spokesperson said: “While the teenager in this case was fictional, Burrin’s intentions were clear and that means he poses a genuine threat to children and young people in the real world.
“Online abuse and grooming is one of the biggest child protection challenges we face so it is right that Burrin faced the courts for his appalling actions.
“While we have every sympathy for people concerned about suspected abusers, we don’t condone members of the public taking the law into their own hands.
“This is because it can run the risk of driving offenders underground, endanger police work and the legal process or result in innocent people being harassed – all of which may put more children at risk.
”If a child is in immediate danger people should call the police on 999.
“Adults worried about the welfare of a child can call the NSPCC’S helpline for help and advice. Children can call Childline on 0800 1111.”
