A 23-year-old transsexual murderer named Paris Green had been allowed to serve her sentence at HMP Edinburgh’s female wing.
However, after it was alleged the 'female' was having sex with other inmates, Green was moved back to a male facility.
Green, formerly known as Peter Laing, had been accused of inappropriate behavior with inmates before.
A source told the Daily Star, “The women want sex and Paris is the only person who can give it to them.”
She was jailed for 18 years after Green and her friends Kevin McDonagh and Dean Smith, were found guilty of murdering Robert Shankland, 45. They had tortured the man for hours before killing him.
According to Metro, A Scottish Ministry of Justice spokesperson said it would not comment on individual cases.
