In 2018, the Offender Database recorded that 28-year-old Joseph Cook was jailed for 15 years for using fake social media aliases to target, blackmail, and rape his victims. Cook—of Bristol—was sentenced at Bristol Crown Court. It was reported that the investigation was triggered in 2016 when a 17-year-old girl disclosed that Cook was demanding indecent images under the threat of leaking pictures she had sent him when she was only 13.
The investigation established that Cook created multiple alias accounts, including one under the name “Jack Barry,” to build romantic trust with young females before obtaining nude images. Bristol Crown Court heard that once he possessed the material, he used threats of exposure to force his victims to record sexual acts. The prosecution reported that in April 2018, while already under active police investigation, Cook used a dating profile to blackmail a woman he knew personally, forcing her to submit to rape by threatening to share private images with her friends and family.
Judicial Findings and Investigative Detail
The court reported that Cook’s behaviour was calculated to cause maximum distress and total control over those who had previously trusted him. Bristol Crown Court heard that forensic analysis of Cook’s seized mobile phones revealed the extent of his predatory digital footprint and the numerous aliases used to trap victims. The investigation established that even the pressure of an ongoing police inquiry did not deter him from carrying out a further rape through digital coercion.
Judge-led proceedings resulted in Cook being handed a 12-year sentence for rape and a three-year consecutive sentence for inciting a child to engage in sexual activity. For his actions in Bristol, he was also made subject to an indefinite Sexual Harm Prevention Order (SHPO). The judge noted the “predatory and persistent” nature of his offending, emphasizing that the consecutive nature of the 15-year total reflected the separate and devastating impact of his crimes against both children and adults.

Monitoring and Public Protection
Cook is managed as a high-risk registered sex offender within the prison estate and will remain a maximum priority for the Avon and Somerset Police Public Protection Unit upon any eventual release. Due to the nature of his conduct—specifically his ability to manage multiple “alias accounts” to groom and blackmail victims—his management is a critical priority. Authorities state that his history of offending while on bail or under investigation proves a complete lack of regard for the law or the safety of the public.
As a registered sex offender for life, the (then) 28-year-old’s details are permanently logged on the national police database. Authorities state that his indefinite SHPO will include the most stringent digital monitoring ever implemented in the region, including a total ban on the use of any alias or unverified social media profiles. Any failure to notify police of his digital hardware, any attempt to contact former victims in Bristol, or any unauthorized proximity to minors will result in immediate arrest to ensure the ongoing safety of the public from his demonstrated pattern of digital sexual predation.
QUESTION – Given that the offender carried out a rape while already under active police investigation for grooming, do you believe that “Electronic Tagging” should be a mandatory legal requirement for every suspect under investigation for sexual offences to prevent further victims?
