A police commissioner has accused paedophile vigilante hunters of undermining investigations as a 39-year-old was caught by three different groups. Mark Cardwell, from Darlington, who has been handed an 18-month prison term after admitting charges of attempted grooming, had been taken in by fake profiles created by three different vigilante groups.
Following his conviction Durham's Police, Crime and Victims' Commissioner Ron Hogg said he felt there 'wasn't a place for vigilante groups in policing...as too many times they can undermine police inquiries'.
There are currently around 75 paedophile vigilante groups in existence.
Cardwell thought he was engaging in explicit messages via an app with different girls, one of them aged just 12.
But he was in fact speaking to adult members of three different vigilant groups: Dark Light, Net Justice and Hunters 24/7.
The 39-year-old boasted how he had a van with a double bed and encouraged one of the 'girls' to lie to her parents about having a sleepover with friends so they could meet.
Cardwell told one of the 'girls': 'I can teach you all sorts.'
The members of one of the groups eventually confronted him at his home and alerted members of his family, leading to his arrest by police.
Robin Turton, for the prosecution, told Teesside Crown Court that conversations between Cardwell and the 'girls' would start innocuously, before he started asking questions such as whether they were wearing a bra and for their breast size.
Cardwell would then request naked pictures, as well as sending them, and encouraged the girls to commit sex acts. Mr Turton said Cardwell, who also pleaded guilty to attempting to engage a child in sexual activity, arranged to meet one of the girls at a supermarket but never went through with it.
When he was arrested Cardwell told police he was in 'self-destruct mode' and claimed to have no sexual interest in children.
His barrister Chris Baker said he had not fully come to terms with his motivation for wanting to contact children aged under 16.
He said Cardwell suffered from depression, low self-esteem and alcohol problems.
Mr Baker said: 'It is clear that as a result of these groups he has lost his partner, his house, his job and his good name...and he has only himself to blame. The judge, Recorder Amanda Rippon said she was familiar with vigilante groups, but added: 'I didn't know there were so many.'
This led Mr Baker to remark: 'I think they call it a cottage industry.'
Durham's Police, Crime and Victims' Commissioner Ron Hogg said: 'Obviously I'm grateful for the evidence which has led to a conviction in this case, but I don't think there's really a place for vigilante groups in policing.
'Too many times they can undermine police enquiries. I know that the public feel confident to submit evidence to the police so that they can do their job thoroughly and professionally.'
His comments come as new figures revealed by MailOnline found nearly half of paedophiles found guilty of grooming a child online before trying to meet them for sex are let off jail by 'lenient' judges.
Durham Police said it did not wish to comment.
Other forces have raised concerns about paedophile vigilante groups.
Last September in County Antrim, Northern Ireland, a man aged in his 50s was confronted at his home by the Silent Justice group and footage of the incident was published online.
