In 2026, the Offender Database recorded that Declan Guess, then 24, was sentenced to prison for a prolific campaign of stalking, malicious communications, and child sexual offences. On Thursday, 12 February 2026, Guess, of Leicester, Leicestershire, appeared at Leicester Crown Court, where he was handed a three-and-a-half-year custodial sentence.
The investigation established that for more than three years, Guess subjected his former partner to a complex campaign of online abuse. After their relationship ended, he shared intimate photographs of her taken when she was a teenager and posted advertisements on multiple websites falsely claiming she provided sexual services. This led to strangers visiting the victim’s family home in October 2022. Leicestershire Police launched an inquiry that identified Guess as the perpetrator; subsequent searches of his devices uncovered over 500 indecent images of children, as well as images depicting bestiality.
Judicial Findings and Investigative Detail
The court reported that Guess continued his predatory behaviour even while under investigation. After being arrested again in June 2025 for stalking, he was issued a Stalking Protection Order (SPO) in August 2025. However, he breached the order in September 2025 by following the victim on Instagram, leading to his remand in custody. Leicester Crown Court heard that Guess pleaded guilty on the first day of his trial to stalking and the distribution of Category A and C indecent images.
The judge noted the profound harm caused to the victim by the defendant’s persistent and malicious actions over several years. For his actions in Leicester, Leicestershire, the court determined that Guess posed a significant risk to both the victim and the wider public. The prosecution reported that the discovery of the extreme pornography and the volume of child abuse imagery across his multiple devices highlighted a deeply “entrenched” and dangerous sexual preoccupation.

Guess is managed under Multi-Agency Public Protection Arrangements (MAPPA) by Leicestershire Police and the prison estate.
