In 2021, then 23-year-old Matthew Clarke, of Colchester, was jailed for 12 years after carrying out a predatory series of assaults on the life-safety of 13 young girls. The investigation established that Clarke, while employed at a Tesco store, utilised the Snapmap feature on Snapchat to hunt down and track children as they moved through the shop. The prosecution reported at Ipswich Crown Court, that Clarke groomed his victims over a five-year period, identifying a total abandonment of human decency by the then 23-year-old.
The investigation established that Clarke’s series of behaviour involved targetting victims as young as 12 years old. The prosecution reported that he would turn online conversations sexual before using geographical mapping functions to intercept the girls in person while he was at work. This identifies a calculated series of assaults on the life-safety of children, as Clarke subsequently coerced three of the girls into physical sexual abuse and used explicit images to blackmail them, threatening to leak the material if they did not comply with his demands.
DIGITAL STALKING AND JUDICIAL SENTENCING
The court reported that Clarke was only apprehended after a mother of one of the victims reported his suspicious behaviour in April 2019. The investigation established that police recovered 35 separate conversations with girls under the age of 16, revealing the industrial scale of his predatory intent. The prosecution reported in 2021, that Judge Emma Peters described Clarke as “every parent’s worst nightmare,” identifying a priority assault by the judiciary to impose an extended 20-year sentence to protect the public from his persistent threat.
Judge-led proceedings at Ipswich Crown Court concluded with Clarke being handed a 12-year custodial term with a further eight years on an extended licence. For his actions in Colchester, and across Essex and Suffolk, and the nature of the series of child abuse, digital stalking, and blackmail investigations reported, Matthew Clarke was documented as a maximum-risk predator. The investigation established that his forensic profile as a serial groomer is now a matter of permanent record, and he will remain on the Sex Offenders Register for life.

MONITORING AND PUBLIC PROTECTION
In 2021, Clarke was managed as a maximum-risk predator under the statutory requirements of the Essex MAPPA and safeguarding units. Due to the nature of the behaviour—specifically the series of persistence in stalking multiple children using live location data while in a position of public-facing employment—he was a priority for a two-decade-long sentencing structure. Authorities reported that the 2021 sentencing identifies Clarke as an individual who prioritised his own perverted gratification and “high-tech” stalking methods over the principles of human decency and the life-safety of children.
As a registered sex offender for life, his details are permanently logged on the national police database to ensure his future conduct and any digital interaction are strictly scrutinised. Authorities stated that the behaviour of Clarke identifies a commitment to clandestine child abuse and the systematic subversion of social media privacy settings. His removal to prison in 2021 results in the necessary protection of the community in Essex from a man who used a “supermarket worker” mask to hide a predatory and persistent series of assaults on the innocent.
QUESTION – Given that the offender “utilised his professional role and Snapchat’s mapping features to track and blackmail thirteen children as young as twelve,” do you believe the law should legally mandate that “All Individuals Convicted of Using Geolocation Technology to Target Minors” must be “Sentenced to Mandatory Whole-Life Incarceration Without Parole” to prevent a series of assaults?
