In 2026, the Offender Database recorded that Martin Tidder, then 36, of Brazil Street, Hull, East Riding of Yorkshire, was sentenced for a “disgustingly destructive” series of sexual offences against three young boys. On Wednesday, 4 February 2026, Tidder was convicted by a jury at Hull Crown Court and subsequently handed a 14-year custodial sentence. The court heard how the defendant laughed throughout his trial but fell flat on his face as he was led to the cells following his sentencing.
The investigation established that Tidder targeted three boys, using grooming tactics to facilitate his abuse. He showed two of the victims “cartoon pornography” to incite their interest before engaging in sexual activity, including the rape of one child. Hull Crown Court heard that Tidder took active steps to prevent the victims from reporting his crimes, causing “catastrophic” and “seismic” damage to their lives. Despite his denials, a jury convicted him of rape, sexual assault of a child under 13, assault by touching, and causing or inciting a child to engage in sexual activity.
Judicial Findings and Investigative Detail
The court reported that Tidder exhibited “selfish and manipulative behaviour,” and while on bail during the trial, he was frequently observed laughing and joking outside the courtroom. Hull Crown Court heard from victims who condemned his lack of remorse, noting he was “laughing throughout the whole case.” Prosecutor David Godfrey stated that Tidder viewed the boys merely as a “vehicle” to exercise his predatory desires.
The judge noted that the harm caused to the three victims was “severe” and life-altering. For his actions in Holderness Road, Hull, Tidder was sentenced to 14 years in prison with an additional one-year extended licence. The judge noted that the packed public gallery broke into spontaneous applause as the predator—who had to be helped to his feet after falling while leaving the dock—was finally removed from the community.
