Transexual prisoner Paris Green, 23, has been moved from a woman's prison amid claims she was having sex with the other prisoners

A transexual murderer who was allowed to serve his sentence in a women's prison has been moved amid claims he was having sex with female inmates.

Paris Green, 23, who was born Peter Laing but identifies as a woman, had been staying on the female wing at HMP Edinburgh.

But Green, who is awaiting sex-change surgery, has been transferred back to the male block amid suspicions she was involved in sexual relationships with other convicts there.

It is the second time Green, who was jailed for at least 18 years for her crime, has been moved for 'inappropriate behaviour'.

In 2013, just weeks after she was found guilty alongside Kevin McDonagh and Dean Smith of the murder of Robert Shankland, she was transferred from Corton Vale women's prison, near Stirling, amid similar accusations.

A source told Daily Star Sunday: 'The women want sex and Paris is the only person who can give it to them.'

Green and her two friends had invited Mr Shankland, 45, to a party in Green's flat in the central Scotland town of Glenrothes in 2013.

There he was tied up, beaten and tortured for hours before finally being murdered.

The behaviour of the three murderers who subjected Mr Shankland to hours of torture in Green's flat was described by a judge as 'utterly depraved'.

During the attack, Mr Shankland was tied up with bedding, battered, kicked and sexually attacked with a rolling pin.

He died as a result of either suffocation or blunt force injuries.

Green's friend Maggie Shields told the trial at the High Court in Glasgow that she visited the flat and discovered the death, before recalling how the trio boasted about the beating.

Miss Shields went on to say the violence had erupted after a row about buying a bag of chips.

As he lay dying, the killers ate ham sandwiches paid for with the proceeds of selling their victim's mobile phone.

The victim's sister Pauline Bell said: 'The whole thing is a joke. We don't believe he really wants a sex change.

'He's just trying to manipulate the system and the tax payer is footing the bill.'

A spokesperson for the Scottish Ministry of Justice, said: 'We would not comment on an individual case.'
