Brian Thomson was convicted of three charges on 20 August 2025 following a trial at the High Court in Edinburgh.
The Crown led evidence which showed Thomson, 67, began sexually offending when he was 12-years-old in 1970.
Over the next seven years, he repeatedly assaulted and raped a young girl to her injury at locations in the East Lothian area.
Thomson was also found guilty of sexually abusing a woman in the 1980s and 1990s, including raping her at a hospital in Edinburgh.
On 16 September 2025, at the same court, Thomson was sentenced to 11 years in custody.
His name has been added to the sex offenders register indefinitely and indefinite non-harassment orders were also granted.
Fiona Kirkby, Procurator Fiscal for High Court Sexual Offences, said: “Brian Thomson has now been held accountable and will face the consequences of his despicable behaviour, which took place several decades ago.
“Despite this, we were able to build a strong case which demonstrated his guilt and the lasting emotional trauma he caused his victims.
“I would like to thank them for reporting these devastating crimes. This prosecution would not have been possible without them.
“This conviction should send a clear message to those who seek to sexually abuse others. COPFS will continue to pursue justice and prosecute sexual offenders – regardless of when the offending took place.
“To anyone affected by similar crime: you are not alone. Please consider reporting your experience to the police when you feel ready and able.
“You will be listened to and supported by our trauma-informed staff as we seek to use all the tools available to us prosecute those responsible.”
