Hull rapist jailed after years of brutal physical and mental abuse

An investigation was launched in June 2025 after Humberside Police received a 999 call from a woman reporting that she had repeatedly been assaulted, called horrendous names, controlled and raped.

She identified John Stanley Twyman as the person responsible.

Officers were immediately deployed and Twyman was arrested the same day on suspicion of breaching a Restraining Order, assault and rape.

During a police interview, Twyman denied the allegations and claimed he was the one being manipulated by the woman and that she was trying to cause arguments with him.

He was charged the following day and remanded in custody to await trial.

Twyman, 28, of no fixed abode in Hull, pleaded guilty to assault and breaching a Restraining Order but denied rape.

A trial was subsequently held at Hull Crown Court, where a jury unanimously found him guilty of rape on Thursday (Apr 27).

Twyman returned to Hull Crown Court on Friday (Sep 11), where he was sentenced to 13 years in prison.

Detective Constable Jan Baldwin, from Humberside Police's Protecting Vulnerable People Unit, led the investigation.

She said: “We wouldn’t be here today without the bravery and strength shown by the woman who took that first step to report the brutality she had been experiencing at the hands of Twyman over a prolonged period of time.

“She is a credit to herself, and her courage cannot be underestimated because despite everything she has gone through, she has remained on board and was willing to give evidence throughout what has been a very long and protracted investigation with many complexities to enable us to stack up the evidence against Twyman.

“This result is also testament to the dedication and tenacity shown by all officers within our Protecting Vulnerable People Unit who are merciless in their pursue of vicious men like Twyman.

“Twyman was unrelenting in his behaviour towards the woman and since he was first arrested and throughout the investigation, he has shown no remorse for the long-lasting impact his actions have and continue to have on her. I am reassured that this dangerous man is off our streets and will be for a very long time.

“Domestic abuse or sexual violence will not be tolerated in any form, and we will always do everything we can to seek justice for those victims and survivors who have suffered and continue to suffer.

“If you have been affected by crimes of this nature, or have concerns about someone who has, when you are ready, please speak to someone you trust and report it to us via our non-emergency number 101. Always call 999 in an emergency or if you are in immediate danger.”
