A 64-year-old man has been jailed for 11 years after being found guilty of 14 sexual offences.
Nand Joshi, 64, raped and indecently assaulted a 14-year-old girl, beginning in 1994.
Joshi, of Queen Adelaide Road, Penge, began his campaign of abuse after the girl arrived in the UK with her mother and younger brother.
He was sentenced to 11 years in prison after being found guilty of seven counts of rape, and sentenced to 18 months in prison after being found guilty of seven counts of sexual assault, to run concurrently.
He has been put on the sex offenders register for life.
Joshi first sexually assaulted the teenager when he, the victim, and others were all sleeping in the same room.
Over a three year period, his victim was raped or sexually assaulted around once or twice a month.
Having access to a property in Bayswater, he would take his victim there to rape her.
Joshi would also write to her teachers requesting for her to leave school early, so he could continue to abuse her.
Detective Constable Manraj Sanghera, from the Sexual Offences Exploitation and Child Abuse Investigation Team said: "The victim has shown great strength of character, she found the courage to come forward and speak about her terrible ordeal and because of this justice has been done."
Joshi was sentenced at Croydon Crown Court on Thursday, after being found guilty at the same court on Wednesday.
He was initially arrested at his home on April 12 last year, and charged on February 26.
