A transgender man was found guilty of assault after having sex with three women without their knowledge while pretending to be born a man using a specially crafted prosthetic penis.
Between June 2010 and March 2016, Tarjit Singh, 32, a biological female called Hannah Walters, abused the victims.
Throughout the relationship, Singh insisted on having sex in the dark and keeping his clothing on so that the strap on the prosthetic penis would not be noticed.
When the victims began to question Singh, he became abusive and manipulative, telling one lady that a relationship was about "more than sex" and that she should learn to communicate about her feelings more.
Singh was found guilty today of three counts of assault by penetration, six counts of assault occasioning real bodily harm, and one count of making a threat to kill after a trial at Snaresbrook Crown Court.
'He looked like a male, and he acted like a guy,' one victim stated.
After discovering his strap-on prosthetic penis a few months into their relationship, the victim claimed she discovered the defendant was not a man.
She admitted to police officers that she felt "very foolish" for believing such things.
Singh informed another victim that he was born a male, had a sex change, and now wanted to be a man again.
After getting a message from the dating website Plenty of Fish in 2014, the third victim met Singh.
Singh informed her that he will undergo sex transformation to become a woman.
He was apprehended after the relationship grew abusive and the victim filed a police report.
During the trial, the prosecution was able to submit mobile phone evidence that revealed Singh's history of visiting websites, including one that made ultra-realistic prosthetic penises.
'These victims have been duped, betrayed, and lied to in the most unsettling and traumatic of ways,' said Melissa Garner of the CPS.
'When one of the victims met the defendant, she was just 16 years old.
'Tarjit Singh, also known as Hannah Walters, pretended to be a man, dressed in men's clothes, and used a man's name.
'He duped three innocent ladies into believing he was a man, and when confronted, he assaulted and bullied them into continuing their relationships.'
'Singh has never admitted to his crimes and maintains that the victims were aware of his gender.'
'In this case, the victims have showed tremendous fortitude by appearing in court and giving testimony.
Singh, from Enfield, will be sentenced on July 27.
