In 2020, the Offender Database recorded that 69-year-old Gary Cooke was sentenced to a further four years in prison for his role in a paedophile ring that targeted boys in the North Wales care system. Following an investigation by the National Crime Agency (NCA) under Operation Pallial, the defendant—of Wrexham—pleaded guilty at Chester Crown Court to four counts of buggery and seven counts of indecent assault. It was reported that Cooke, who also used the name Mark Grainger, was already serving a 14-year sentence handed down in 2015 for a catalogue of serious sexual assaults against young boys.
The investigation established that Cooke used his various roles, including children’s care home worker, judo instructor, and professional wrestler, to exploit vulnerable children. The NCA reported that one of the new victims was targeted in 1977 at the age of 14, just two weeks after arriving at a care home in Cheshire run by the Bryn Alyn group. The prosecution reported that Cooke manipulated this victim through fear and bribery for nine months, eventually discharging him rapidly when the boy attempted to report the abuse.
Judicial Findings and Investigative Detail
The court reported that Cooke was a systematic and devious predator who cherry-picked his victims. Chester Crown Court heard that the second victim, also abused between the ages of 14 and 17, was plied with alcohol at Cooke’s home and taken to parties at pubs and clubs in Chester to be further exploited. The investigation established that Cooke frequently took photographs of the attacks and used them, along with images of other boys, to further groom and silence his victims.
NCA Senior Investigating Officer Philip Marshall presided over the findings, noting that Cooke had completely eroded the confidence of those in his care. For his actions across North Wales and Cheshire, the four-year sentence was added to his existing 14-year term. The judge noted the incredible courage of the survivors who relayed excruciating memories from the 1970s and 1980s to ensure their abuser faced further justice for the systematic nature of his crimes.

Monitoring and Public Protection
Cooke is managed as a high-risk Category 1 dangerous predator within the national prison estate. Due to the nature of his conduct, which involved the organized grooming and abuse of children in state care, his management is a maximum priority. Authorities state that the use of his professional status as a wrestler and instructor to gain access to victims indicates a long-term pattern of predatory behavior that requires the most stringent level of oversight by the Public Protection Unit.
As a registered sex offender for life, Cooke’s details are permanently logged on the national police database. Authorities state that his history as a central figure in a paedophile ring means any eventual release would be subject to the highest level of Multi-Agency Public Protection Arrangements (MAPPA). Any contact with minors or attempts to return to roles involving children in Wrexham, Chester, or North Wales will result in immediate intervention to ensure the ongoing safety of the public.
