Steve Adams first abused the girl in January 2019 when she was a teenager and continued for a year, until in January 2020, the girl disclosed her ordeals to a safeguarding officer.
The 67-year-old from Marine Parade, Sheerness was arrested and later charged with sexual assault.
He denied the allegations but a jury at Maidstone Crown Court found him guilty and on Thursday 29 August 2024 at the same court was jailed for a total of 13 years.
Investigating officer, Detective Constable Gemma Willis said: ‘Adams took advantage of a young woman for his own sexual gratification.
‘His prison sentence means he can no longer harm anyone else and I hope that brings some comfort to the victim.’
