A "calculating and violent" 21-year-old has been found guilty of raping a woman in her own home - and detectives believe there may be further victims.
Stefan Melbourne, of Sherwood Avenue, Streatham, was convicted at Woolwich Crown Court yesterday after his victim was attacked in Clapham in January 2013.
Detective Inspector Jim Pryde, from the Met Police Sexual Offences, Exploitation and Child Abuse Command, said: "Melbourne has shown himself to be a calculating and violent individual.
"He deserves a lengthy sentence and will be a registered sex offender on release from prison.
"The victim in this case was naturally scared of having to go to court but was determined to see justice done and her courage and perseverance has resulted in his conviction.
"I believe there may be other victims Melbourne has raped and I urge them to contact police. Specially trained officers will help you through this process."
Investigating officer Detective Constable Jivan Saib added: "The bravery of the victim in this case should be commended. We worked hard with our partners at Rape Crisis to fully support the victim which resulted in her feeling able to give evidence, leading to today's conviction."
The 28-year-old victim attended the haven anonymously after the offence took place on January 22, 2013.
She said Melbourne, who she knew, had visited her home in SW4 on the pretence that he had business in the area and needed somewhere to stay the night.
He then threatened her with violence and raped her.
The victim initially was too scared to pursue the matter but over time felt strong enough to support the prosecution.
Sentencing will take place on a date to be set, police said.
Anyone who thinks they may have been a victim of Melbourne should contact police in confidence on 101 or the Sexual Offences, Exploitation and Child Abuse Command directly on 020 8721 4607.
Melbourne was found not guilty of two further counts of rape.
