This video shows the moment a 32-year-old takeaway pizza chef thought he was meeting a 13-year-old girl but was instead confronted by Dark Justice paedophile hunters.
Muhammad Saleem attempted to sexually groom the schoolgirl online and detailed in graphic detail what he wanted to do with her.
He referred to himself as her 'boyfriend' and then demanded intimate pictures of her in the bath because he 'had a right' to see her.
He also asked what her favourite sexual position and if she wanted to 'suck his lollipop'.
But when he arranged to meet her in Newcastle's Times Square he was instead confronted by the paedophile vigilante group.
The pizza chef denied grooming the 13-year-old girl and tried to wipe all chat history by putting his phone onto factory reset. He has now been jailed for 14 months.
The paedophile hunters asked him: 'You don't know? You don't know how old this girl is?'
Looking at the floor, Saleem replied: 'No.'
They then said: 'So she's not 13 years old?'
The pizza chef replied: 'I don't know mate.'
He then tried to walk away from the paedophile hunters and attempted to shield his face from the camera.
Saleem was then seen trying to quickly scrub all the memory from his mobile phone.
He was arrested by police who charged him with attempting to meet a child following sexual grooming.
Saleem, from Newcastle, initially admitted the charges, but then appealed to changed his plea which was rejected at Newcastle Crown Court.
He has now been jailed for 14 months.
Dark Justice are an undercover organisation who pose as children online and arrange to meet sexual predators who are seeking to engage in sexual activity with underage girls and boys.
Their successful activities have led to 52 convictions and 28 offenders have been jailed.
A member of the group said: 'Saleem was an absolute parasite. I think that the sentence was quite good. It is nice to see that he is behind bars, even though it could have been a little bit longer.
'He showed absolutely no remorse for his actions and he even tried to destroy evidence to cover his own tracks.
'He messed around the courts by appealing to change his plea, even though there was no defence.
'He was just trying to buy more time.
'I am glad that the judge was able to see that.
'He told us that he had other girls giving him oral sex in the takeaway where he worked. He is a danger to children and is a risk to the public.
'He really was just vile, a nasty piece of work.'
In April a court ruled that Dark Justice could continue to pose as children online to catch sexual predators.
Legal teams acting for two men who were caught by Dark Justice allegedly attempting to sexually abuse minors had argued that the use of evidence gathered by such operations 'diminished the integrity of the court process' and that the groups should be regulated.
But a judge at Newcastle Crown Court ruled that there was no legal requirement for the activities of Dark Justice to be subject to controls.
Dark Justice – two men in their 20s who keep their full identities a secret – operates fake online profiles of minors, with photographs provided by volunteers. If someone arranges a meeting with a person they think is a child, Dark Justice waits with a video camera at the location and the resulting video is posted online.
Scott, 26, and Calum, 22, based in Newcastle, both quit their jobs in the digital media industry in October 2014 to focus on Dark Justice full time.
