A trans Metropolitan Police volunteer posed as a 16-year-old girl when he first began talking to the woman he is accused of raping, a court has heard.

James Bubb, 27, who now identifies as a woman named Gwyn Samuels, allegedly raped the woman he was in an on-off relationship with over a five-year period.

A trial at Amersham Law Courts on Monday heard that the pair had met on the online chat site, Omegle, while Bubb was posing as a teenage girl and that they had spoken about a sexual practice known as BDSM.

Jurors previously heard the woman had told police Bubb, of High Street, Chesham, Buckinghamshire, went on to use 'BDSM and kink as a way of creating control' throughout their relationship.

The complainant, who cannot be named for legal reasons, told the court on Monday: 'When I met James on Omegle, I didn't know that it was James at first, they introduced themselves as a teenage girl so I was more concerned than anything else, and then kind of just talking to them about maybe this isn't what they should want to look at at their age.'
