A double rapist, who had a £10,000 sex change operation behind bars, has been put in segregation at a women-only prison after making unwanted sexual advances on inmates.

Martin Ponting, 50, a father-of-three, became Jessica Winfield in jail after being sentenced to life imprisonment in 1995.

She was moved in March this year from male-only HMP Whitemoor, in Cambridgeshire, to HMP Bronzefield in Surrey – Europe’s largest female prison.

Now, it has emerged that Jessica, who still has a pen1s, was segregated last week due to reports of ‘her’ making inappropriate advances on her fellow inmates.

A source told The Sun: ‘It beggars belief why a convicted double rapist like Jessica is allowed to mix with females despite still have her penis intact.

‘Prison bosses were worried she would try it on with inmates and their fears have come true. Inmates were furious to be lumbered with a convicted rapist in the first place and they’re even more angry now.’

Pilley, who was sentenced to life in jail for the kidnapping of a taxi-driver, Linda Charlesworth, in 1981, became the first prisoner to undergo a sex change.

Then in 2009 a High Court ruling enabled transgender prisoners to transfer to different sex jails. sun
