Norman Bowen-Jones, a convicted murderer who killed a pregnant woman in a barbaric sexually-motivated attack, has been jailed again after being caught trying to meet an underage girl at the Royal Armouries in Leeds.

Bowen-Jones, 45, was sentenced at Leeds Crown Court after being exposed by the paedophile hunter group, Predator Exposure.

He had contacted several child decoy profiles last year, including one he believed to be a 14-year-old girl. He sent her pictures of his penis and asked for photos of her, suggesting they meet at the Royal Armouries.

Bowen-Jones was confronted by the hunter group, who livestreamed the encounter over the internet. He had also contacted other decoy profiles run by the same group, suggesting a meeting at Leeds Railway Station, but did not go through with it.

He admitted attempting to cause or incite a child to engage in sexual activity, four counts of attempting sexual communication with a child, arranging or facilitating commission of a child sex offence, two offences of attempting to cause a child to engage in sexual activity, attempting to meet a child following sexual grooming, and two of making indecent photos of children.

In mitigation, Andrew Stranex said that Bowen-Jones was "like a fish out of water" since his release from prison and was struggling to adjust to a world he was unfamiliar with.

The judge, Recorder Alex Menary, acknowledged that Bowen-Jones was "struggling to adjust" but jailed him for 32 months, adding that his life licence will remain in place, meaning he could be returned to prison at any time after serving his latest sentence.

Bowen-Jones was also given a lifelong sexual harm prevention order (SHPO) to curb his internet use and placed on the sex offender register for life.

The 45-year-old was previously jailed for life in 1997 for the murder of 29-year-old Lesley Fox, who was four months pregnant at the time. He and his friend Timothy Dunn, who was 15 at the time, had fantasised about having sex with her and killing her, carrying out the horrific plan on October 12, 1996.

Fox was subjected to a prolonged and violent sexual assault before being strangled by Bowen-Jones. The sexual assault continued after her death.

Bowen-Jones and Dunn were deemed "very dangerous" by the presiding judge at their sentencing and were told to serve a minimum of 13 years.
