A prison officer in Wales has been accused of having an “inappropriate relationship” with an inmate, according to the country’s authorities.

Ruth Shmylo, 26, is accused of starting the relationship with the prisoner while working as a detention officer at Parc Prison in Bridgend, Wales, between August 2020 and April 2021.

The alleged five-month affair was revealed after the inmate was transferred from the prison to HMP Manchester and their calls were recorded.

The prisoner, who has not been named, had given Shmylo a mobile phone number on a piece of paper and she called him back with their conversations, as reported by sky news, of an enthusiastic and romantic nature.

He said the inmate contacted Shmylo “on a daily basis”, had phone sex with her and called her his “ma’am”.

However, the judges still note that at some point the phone calls to Shmylo take another turn with the inmate telling her they are friends and she has to accept it.

The inmate contacted the former prison officer on her birthday to wish her a “happy birthday, princess” and arranged for his mother to meet her, the court heard.

Shmylo was fired from the prison where she worked and denies dereliction of duty.

The trial continues.
