In 2021, the Offender Database recorded that 63-year-old Robert Sharpley, a retired Thai boxing instructor, was jailed for three-and-a-half years for sexually assaulting an underage student. Sharpley—previously of Bolton, Greater Manchester, but living in Pen y Bont, Abergavenny, near Monmouth at the time of his sentencing—abused the teenage girl during the early 1990s. It was reported that the investigation was launched years later when the victim read a news article about other instructors acting inappropriately and found the courage to report her ordeal to the police.
The investigation established that Sharpley used his position of authority at a Thai boxing gym in Bolton to groom his victim. Bolton Crown Court heard that the abuse began during a birthday party at his home, where he took the girl aside and kissed her. The prosecution reported that Sharpley later invited her to his house under the guise of babysitting while his wife was away, only to ply her with cannabis and persuade her to perform sexual acts, which developed into a “fully fledged affair” involving ecstasy and nightclubs while she was still a minor.
Judicial Findings and Investigative Detail
The court reported that Sharpley’s conduct was an abhorrent abuse of power designed to satisfy his perverted sexual desires. Bolton Crown Court heard that the defendant forced the girl to lie to her parents and exploited her vulnerability as her teacher. The investigation established that Sharpley denied the sexual relationship for two years following his 2019 arrest, only pleading guilty to two counts of indecent assault on the first day of his trial when faced with the evidence of his grooming behaviour.
The Honorary Recorder of Bolton, Judge Martin Walsh, presided over the sentencing, describing the case as a significant breach of trust. For his actions in Bolton and his subsequent life in Monmouthshire, Sharpley was removed from the community to serve his 42-month sentence. The judge noted that the victim had been effectively groomed by Sharpley in his capacity as an instructor, and his actions had a long-lasting impact on the young girl that he had failed to consider.

Monitoring and Public Protection
Sharpley is managed as a high-risk registered sex offender within the Abergavenny and Monmouth area following his release. Due to the nature of his conduct—which involved the systematic grooming and sexual exploitation of a student under the guise of sports instruction—his management is a priority for the Gwent Police Public Protection Unit. Authorities state that his history of using his professional status to access and abuse children indicates a predatory methodology that requires permanent oversight.
As a registered sex offender for life, the 63-year-old’s details are permanently logged on the national police database. Authorities state that his notification requirements ensure he must inform police of his residency and any intended travel. Any failure to notify police of his movements in Monmouthshire, any attempt to return to sports coaching or martial arts instruction, or any unauthorized proximity to minors will result in immediate arrest to ensure the ongoing safety of the public from his demonstrated pattern of predatory sexual violence.
QUESTION – Given that the offender used a sports club and a “teacher-student” dynamic to groom his victim, do you believe that “Life-Long Bans” from all sports coaching should be automatically applied to any instructor convicted of a sexual offence, regardless of the victim’s age?
