A man who was trapped by vigilantes after trying to groom a teenage girl on the internet has been jailed for 12 months.
57-year-old John Rudd thought he was talking to a 14-year-old called Donna but it was, in fact, a group called Dark Justice.
He then arranged to meet her in Gateshead where the vigilantes filmed him and handed him to the police.
