Guy Watson, 33, the Birmingham Male Rapist, was found guilty of seven sexual offences in June and was back in Cardiff Crown Court today (Wednesday, September 18) where he was sentenced to eight years.
Guy Watson was arrested on Christmas Day 2022 after officers found videos on his mobile phone of him sexually assaulting a man in his flat.
The victim was traced, and further videos of the assault were also found on the victim’s mobile phone.
During the sexual assaults, the victim can be seen and heard to be in a deep sleep.
Guy Watson denied the offences but was found guilty of seven charges, including five of sexual assault and two of causing a male to engage in sexual activity without consent.
The officer in the case, Detective Constable Christopher Day, from South Wales Police, said:
“This incident has had a profound effect on the victim’s mental health, his employment, and his relationships.
“In April 2022, he and Guy Watson were socialising in Guy Watson’s flat in Stanwell Road, Penarth, where they were drinking and listening to music.
“The victim cannot recall anything further from this point, and the first he knew of being sexually assaulted was when videos were found on his mobile phone approximately a month later.
“We hope today’s sentencing gives the victim some comfort as he continues to rebuild his life and put this trauma behind him.”
Guy Watson was also made subject to a 10-year Restraining Order not to contact the victim and a requirement to sign the Sex Offenders Register indefinitely.
South Wales Police takes all reports of sexual violence extremely seriously, and it is never too late to report a crime.
