The details: Grinham appeared at Ipswich Crown Court on Tuesday 22 July where he received 13 years' imprisonment with an extended licence period of five years for the rape charges. He was given a three-year concurrent sentence for causing ABH.
A jury found him guilty of all charges on 29 May 2025 following an eight-day trial.
Grinham was also made subject of an indefinite Sexual Harm Prevention Order and indefinite Restraining Order, and has been placed on the Sex Offenders Register for life.
What they're saying: Detective Constable Jennifer Botting, the officer in charge of the case, said: "Grinham carried out horrific abuse to his victim, causing long-lasting effects that have impacted her life and those around her.
"I want to commend her for the extraordinary courage she has shown in coming forward and seeing this case through to the end. We hope today's outcome brings some measure of justice and reassurance – not only to the victim in this case, but to others who may be suffering in silence."
DC Botting also thanked DC James Lait, who was the initial officer in charge before she took on the investigation.
"Suffolk Constabulary remains committed to supporting survivors and bringing perpetrators to justice, no matter how long it takes," she added.
