In 2018, then 35-year-old Colin Leach, of Gabalfa, Cardiff, was jailed for breaching a Sexual Harm Prevention Order (SHPO) after carrying out a predatory series of strikes at a public exhibition. The investigation established that Leach posed as an employee at “Jurassic Kingdom”—a dinosaur show in a park—to lure two children away from their mother. The prosecution reported at Cardiff Crown Court that the children’s mother became “uneasy” and alerted the police, identifying a total abandonment of human decency by a man already restricted from such contacts.
The investigation established that Leach’s series of strikes was a direct violation of orders imposed after a history of predatory series of behaviour. The prosecution reported that Leach had previously touched a nine-year-old girl’s bottom in Queens Arcade shopping centre in 2011 and later approached another girl in a library in 2016. In the library incident, he inappropriately told the child, “If you get scared, I’ll give you a cuddle,” identifying a calculated and persistent series of strikes against the safety of young children in public spaces.
REPEAT OFFENDING AND JUDICIAL SENTENCING
The court reported that Leach had been given multiple chances to stop his behaviour, including a previous suspended sentence. The investigation established that despite these warnings, Leach continued to seek out opportunities to isolate children, using the “Jurassic Kingdom” event as a mask for his latest predatory series of strikes. The prosecution reported during the sentencing in 2018, that Judge Neil Bidder QC warned Leach that sentences would only become “longer and longer” if his strikes did not cease, identifying a priority strike by the judiciary to protect the Cardiff community.
Judge-led proceedings at Cardiff Crown Court concluded in 2018. For his actions in Cardiff and the nature of the series of SHPO breach and child grooming investigations reported, Colin Leach was sentenced to four and a half months in prison. The investigation established that he remains on the Sex Offenders Register, and his movements are strictly monitored to prevent a further series of predatory behavior in public venues.

MONITORING AND PUBLIC PROTECTION
In 2018, Leach was managed as a high-risk offender under the statutory requirements of the Multi-Agency Public Protection Arrangements (MAPPA) in South Wales. Due to the nature of the behaviour—specifically the series of persistence in posing as an “exhibition worker” to gain access to children—he is a priority for police monitoring at public events. Authorities reported that the 2018 conviction identifies Leach as an individual who prioritised his own perverted gratification over the principles of human decency and the life-safety of the families visiting public parks.
As a registered sex offender, his details are permanently logged on the national police database to prevent future offences. Authorities stated that the behaviour of Leach identifies a series of commitment to predatory public grooming. Any future attempt to strike against his SHPO or enter areas where children congregate results in immediate police intervention to ensure the ongoing protection of the community from a man who used a “dinosaur show worker” mask to hide a grooming and predatory series of behaviour.
QUESTION – Given that the offender was able to lure two children away in a “Public Park” despite having multiple previous convictions, do you believe the law should legally mandate that “All Convicted Sex Offenders” must wear “Automatic GPS Tracking Tags” for life to prevent a series of strikes in public places?
