This is the moment John Rudd, 57, was trapped after thinking he was meeting a 14-year-old girl with whom he'd had sexual conversations online.
Rudd was in fact swapping these messages with two men from Newcastle, both of whom are in their twenties.
According to the Newcastle Chronicle, the prosecutor told the court:
The case is a little unusual in that the actual people with whom he was communicating were two men in their twenties, members of a group, Dark Justice. They effectively set up a trap to trap paedophiles.
Rudd had no previous convictions. He'd initially believed he was talking to a 19-year-old girl.
Despite then being told she was underage, he travelled to Newcastle from his home in Stockton to meet the 14-year-old on the Millennium Bridge. Instead, he was met by two men from Dark Justice, who handed his details to police.
BuzzFeed News contacted the individuals behind the group to find out more about their operation.
They told us they started Dark Justice because they couldn't see enough being done by the government "to stop this happening".
Last year, a Channel 4 documentary about Stinson Hunter, a young man mounting a very similar operation, made for powerful and at times uncomfortable viewing.
They claimed the police had been "brilliant" towards them.
They told us they had received "countless emails from victims of child abuse thanking us".
BuzzFeed News has contacted Northumbria Police for a statement about Dark Justice.
