Raymond Nyiam, also known as Otu Nyiam, was convicted of two charges on 15 April 2025 following a trial at the High Court in Edinburgh.
The 35-year-old's offending took place after he encountered both victims at a nightclub in the capital on 19 February 2019.
He raped both teenagers at a flat when they were either asleep or unconscious due to the effects of alcohol, meaning they were incapable of giving consent.
On 26 August 2025, at the same court, Nyiam was made subject to an Order for Lifelong Restriction (OLR).
He must serve a minimum of four years in custody before he can be considered for release into the community by the Parole Board.
His name has been added to the sex offenders register indefinitely. He was also given an indefinite non-harassment order.
Fiona Kirkby, Procurator Fiscal for High Court Sexual Offences, said:
“Raymond Nyiam systematically pursued these young women, who had the right to be safe after enjoying a night out.
“Instead, he exploited their vulnerability to rape them when they were incapable of giving consent.
“Nyiam has now been held accountable for his depraved actions, which would not have been possible without the women affected by his crimes coming forward.
“I hope this prosecution sends a clear message that this type of offending will not be tolerated and has no place in society.
“I would urge anyone affected by sexual abuse to consider reporting it when they feel ready and able to do so.
“You will be listened to and supported as we use all the tools available to us to help protect communities in Scotland by prosecuting those responsible.”
