A former soldier who carried out a string of sex attacks has been jailed indefinitely.
Judge Nicholas Price QC described Brian Witty, 41, as a "predatory rapist" as he told the former Territorial Army Parachute Regiment captain he would serve at least eight years before he could be considered for release.
Witty, who told one victim who rejected him: "I don't believe this, I'm a good-looking bloke", was convicted last month of three rapes and one sexual assault on four women between 1995 and 2011.
Judge Price, sentencing Witty at Kingston Crown Court, told him he was a "bullying, self-obsessed, arrogant sexual predator who was determined to indulge in fulfilling your desires, irrespective and dismissive of their pleas".
Witty, of Twickenham Road, in Teddington, south-west London, met two of his victims through a dating website and preyed on the others after chance encounters in bars. But after he was arrested he claimed the sexual encounters were consensual.
Judge Price jailed him for six years for a rape in 1995, to run concurrently with three separate indeterminate sentences for two other rapes and a sexual assault. Witty was told he would serve a minimum of eight years behind bars.
Handing down his sentence, Judge Price said: "There is no doubt in my mind that you present a very real danger to women, and the only appropriate sentence in your case is one of imprisonment for public protection. It is clear to me you set out to prey on vulnerable women. You hid your base intentions behind a veneer of charm and lulled your victims into a false sense of security."
Despite being arrested and interviewed after the rape at his home address in 1995, again after a sexual assault in 2006 and after another rape in 2008, charges were never brought by the Crown Prosecution Service.
Judge Price told Witty: "The consequences meant you considered yourself to be untouchable by the authorities. With the benefit of hindsight it is perhaps too easy to say that, had you been successfully prosecuted in 1995, you may well not have been free to commit these other later serious offences."
Witty was placed on the sex offenders register for life, and if released will be on licence for life.
