A man claimed he raped his own mother because of the stress of being accused of raping his girlfriend.
The 29-year-old armed himself with a screwdriver and attacked his mother while on bail for sexually assaulting his partner in a jealous rage.
The man, from Merseyside, has been jailed for 15 years at Liverpool Crown Court.
He admitted the cocaine-fuelled attack on his mother and was found guilty of raping his girlfriend in a trial that ended in a violent outburst in the dock.
After being warned by a judge that he faced a long jail sentence, the rapist flew into a rage and jumped to his feet, turning to face his former partner who was sitting in the public gallery behind him.
He yelled, “you f***ing b****” before launching himself at a glass barrier, kicking and smashing it.
The rapist, who cannot be named for legal reasons, was intercepted by two dock officers and a court policeman.
Judge Elizabeth Nicholls said the man was violent, controlling and had demonstrated “the most intimidating and frightening behaviour towards women”.
She said he “sought to limit his responsibility” for raping his mum, adding: “You suggested you only behaved in this fashion because you were facing false allegations.
“It is such a lack of insight that causes the most concern to this court.”
The judge she had “no doubt” he was dangerous and a risk to women due to his violent past and lack of empathy.
Judge Nicholls said: “A psychiatric report describes you as having a potential dissocial personality disorder.
“In particular it expresses concern with regard to your callous unconcern for others, low tolerance for frustration and incapacity to experience guilt.
“Whilst on bail you committed these horrific offences upon your mother.
“You still seek to explain these away and excuse your conduct away by referring to the stress of the situation that you found yourself in.
“Most people having been arrested for a serious offence of rape may try to address their issues. It doesn’t appear that you have done so.”
His trial had heard how he attacked his girlfriend by hitting her in the face three times and kicking her while she was on the floor.
Neville Biddle, prosecuting, said the attack began while the couple were in bed. He added: “It was a nasty, sustained and unpleasant assault.”
On a separate occasion the attacker “assaulted her in a most unpleasant way” after alleging she was cheating on him, the court heard. The ordeal – too graphic to describe – continued with him forcing her to perform a sex act.
While on bail for the offences, he raped his mum in her bed at around 4am after a night of drinking and taking drugs.
Mr Biddle said: “He was shouting ‘mum, mum’. He put his hand over her mouth and he held a screwdriver.”
He fled in his mum’s car and was arrested at Jodrell Bank Observatory.
The man was found guilty of assault causing actual bodily harm, rape and sexual assault. He earlier admitted two counts of rape and one of sexual assault against his mother.
His previous convictions included assault, causing actual bodily harm and battery against two ex-girlfriends.
Mr Biddle said the man’s former partner had provided a victim impact statement but not the man’s mother had not. He told the court: “Unsurprisingly, she has declined. What could a mother say in these circumstances?”
Brian McKenna, defending, argued his client was not dangerous, as defined in law. He suggested the man did not pose a “significant risk” and should not receive an extended sentence.
Mr McKenna said his girlfriend suffered “a degree of psychological harm” but suggested it was not severe.
He said the man intended to address issues like anger management, victim empathy and “thinking skills” in prison.
However, he said he still “strenuously denied” raping his ex and his outburst was due to the “extremely stressful” guilty verdict and provocation from a member of the public.
Judge Nicholls jailed him for 15 years, plus six months for contempt of court, with an extended six years on licence.
It means he will spend at least two thirds of the custodial term – 10 years and four months – behind bars.
He will only be released if a parole board decides it is safe and will be on licence until he is 50.
The man must also sign on the Sex Offenders Register for life.
