A man who called an escort to his flat and then raped her has been jailed for seven years, but his co-defendant has gone on the run.
Sadiq Ali, of Minterne Way, Hayes, demanded the 19-year-old victim perform a sex act during the violent sexual assault at an address in Blyth Road, Hayes, a court heard.
He had called the escort agency she worked for in the early hours of May 26, 2012.
Ali left the room after the attack, and another man, Mohammed Abdihakim, 22, entered and also forced her to perform the sex act.
Ali, 23, was found guilty of rape, attempted rape, and false imprisonment after a trial which took place between September 23 and October 4.
He was sentenced at Isleworth Crown Court on Friday, December 13.
The woman, a student who became an escort to pay for her studies, suffered no physical injury, and bravely gave evidence in front of her attackers during the trial.
An impact statement describing the effect the ordeal has had on her was handed to Judge Andrew McDowall before he sentenced Ali to seven years for rape, three years for attempted rape, and one year for false imprisonment, each to run concurrently.
Ali, a graduate said to be of previous good character, is expected to serve half of that time and half on licence, and will be on the sex offenders’ register for an indefinite period.
Abdihakim, formerly of White City, Kensington, was also convicted of rape and false imprisonment. He was released on bail after the trial and has gone missing.
It was said in court that his last known mobile phone had transmitted signals near Mogadishu, the capital city of Somalia.
Another suspect absconded before the start of the trial.
DC Adam Lewis said: "This was a horrific attack by three males on a lone female victim.
"Police are still actively pursuing the two outstanding suspects in this case. The MPS are committed to pursuing any allegations made to them of a sexual nature."
