A rapist who repeatedly attacked a businesswoman in her hotel room has been jailed indefinitely.
The judge said Hassan-Noor should be deported after leaving prison
Crack addict Ali Hassan-Noor, 24, threatened to kill the woman after forcing his way into her room in central London last May.
Unemployed Hassan-Noor, from Kentish Town, north London, pleaded guilty to three counts of rape and robbery.
The judge at Southwark Crown Court recommended he should be deported to Somalia after serving his sentence.
The court heard the woman, a married mother in her 40s, had travelled from her home in the north-west of England earlier the same day.
'Humiliation and terror'
When Hassan-Noor burst into the room he shouted: "Shut up, I've got a knife, you scream and I will kill you."
He then beat her before repeatedly sexually assaulting her and stealing her mobile phones and bank cards.
The woman, said as her "humiliation and terror" mounted she did her best to "switch off", realising resistance was not only futile but could end in her murder.
Hassan-Noor stole £300 from her accounts and was identified using CCTV from the hotel and security cameras at cash machines he used to withdraw her money.
He had maintained his innocence but changed his plea minutes before his trial was due to begin last month.
Judge Deborah Taylor told him: "There is little to be said in your favour.
"The fact you had taken drugs prior to this offence is no excuse for the conduct that followed."
She explained that once time on remand had been considered he would have to serve a minimum of four years 85 days before he could be considered for parole.
In a statement, the businesswoman said: "I hope my case will give other victims of rape the confidence to come forward and to contact police.
"The support I have received both during the investigation and in preparing to relive my ordeal in court has been fantastic."
Case officer, Det Sgt Ivon Beer, said: "The level of aggression displayed by Hassan-Noor, combined with the degradation the victim suffered, makes this one of the worst rape cases this unit has dealt with."
