A TRANSGENDER double rapist who was moved to a women’s jail has been put in segregation after making unwanted sexual advances to inmates.

Jessica Winfield, 50, who as Martin Ponting raped two young girls, was moved after starting gender reassignment treatment on the NHS — despite still having a penis.

She was segregated last week after being reported for making inappropriate advances to other prisoners.

A source said: “It beggars belief why a convicted double rapist like Jessica is allowed to mix with females despite still having 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.”

Ponting was jailed for life in 1995 and began transitioning to a woman once behind bars.

The Sun revealed in March the switch to women-only HMP Bronzefield in Surrey. One of the rapist’s victims called it “a kick in the teeth”.

Winfield is being held in a segregation block at the Category A prison, which is also home to killers Mairead Philpott, Joanna Dennehy and Shauna Hoare.

Prison bosses are undecided whether they can put her back among female prisoners or return her to male-only Whitemoor in March, Cambs.

Winfield’s ex-wife Sharleen Ponting, 45, said she is not surprised by the problem at Bronzefield. She added: “This was inevitable. I knew it would happen.

“Whoever thought it was a good idea to put a double rapist in a women’s jail was bonkers.

“He is a proven predator and his mentality will never change, no matter which gender he is.

“He should never have been put in a women’s prison, he belongs in a male prison.

“He is a dangerous man and it beggars belief why he was allowed to mix with women.”

The Ministry of Justice declined to comment.
