The brother of caged paedophile Michael Dunn said the violent sex offender's 27 years jail sentence was not enough - and said he would 'build the gallows himself to hang him.'
Robert Dunn spoke outside Teesside Crown Court after his 57-year-old brother wasjailed for abusing four girls and women over five decades.
He said Dunn deserved more than the 27 year sentence and the judge had been 'very lenient.'
Michael Dunn wept in the dock during the sentencing, which followed his conviction for 10 rapes, three charges of false imprisonment and three charges of indecent assault after a trial in January.
Jurors were told that Dunn used a bag of dust and a panel to camouflage the hole where the girl was kept, concealing her from the police on eight or nine occasions.
Judge Tony Briggs said previous reporting was wrong to liken the case to that of Josef Fritzl, the Austrian who kept family members captive, as Dunn's runaway victim wanted to be hidden from the authorities.
Richard Bennett, prosecuting, said Dunn knew the girl had already been sexually abused by a relative when he raped her, cynically telling her that she had had sex "before so she knew how it felt".
His kept his two German Shepherd dogs near the hidey hole to put off the police from looking too hard for her, the court heard.
"Paranoid" Dunn imprisoned and raped a second female victim, subjecting her to repeated violence, and filled his house with cameras, locks on the outside of doors and alarms.
He also groomed and sexually assaulted another vulnerable teenager in the1990s, giving her alcohol and cigarettes.
Dunn also raped a girl aged 10 or 11 when he was 19, telling her "this is what boyfriends and girlfriends do" and said she was not to tell anyone.
Years later, after she had told her mother, Dunn threatened to have herprosecuted for slander.
Rod Hunt, defending, said Dunn was undergoing tests for cancer, and partlyblamed his client's violence and sexual offending on his alcoholism.
Judge Briggs told Dunn, a father-of-six, he had a "volcanic temper, particularly when you are in drink".
The judge said the case was horrific and described it as "repellent" that hewould pick on a girl who had already been abused.
A pre-sentence report said he posed a risk of serious harm to women.
The judge said: "You still deny any responsibilities for your actions, sayingthey have lied to get you wrongly convicted."
Outside court, Detective Chief Inspector Warren Shepheard said: "This is the most harrowing, disturbing, complex case I have dealt with in my 25 years' service."
