The alleged victim told a male friend that she had been groped and he told Mr Christoforou that he “simply couldn’t touch women that way”, the court heard.”She did not think it was amusing; she found it upsetting,” said Mr Hearnden. “The fact it happened in front of work colleagues was a particular cause of upset and anxiety.” Christaggelis Christoforou is a former JP Morgan banker, the court heardCredit:Dylan Martinez/Reuters Following the woman’s complaint to police, Mr Christoforou told officers that the victim had said her breasts were her “best asset”.”He completely denied he had squeezed her breasts,” said Mr Hearnden. “He denied that he had burrowed his head actually into her chest, or motorboating as he called it.”Mr Hearnden told jurors that Mr Christoforou claimed “it was just a bit of fun”, but added: “Just a bit of fun is not a defence [to the charge].”His alleged victim told the court: “We were in a group and while we were talking, Chris reached out and touched my breasts.”He did that a couple of times. I would described it as patting. I remember saying ‘no’ and being quite put out about it. I remember asking him to stop.”I don’t like that sort of attention or approach. He told me again I had no sense of humour, that it was just fun.” He must have thought the whole thing was funny because he appears to be laughing and he even reaches out to have another goRichard Hearnden, prosecuting Moments later, Mr Christoforou launched the “motorboating” attack, it is claimed.She said: “He leaned his head down and pushed his face between my breasts inside my top and moved his face around. At that point, I pushed him away from me.”Mr Christoforou’s barrister, Giles Newell ,suggested that the banker had leaned forward and lowered his head because he had dropped his phone.The alleged victim replied: “That’s incorrect.” She told the court that she found his sense of humour “offensive and a little vulgar”.Mr Christoforou, from Croydon, south London, denies one charge of sexual assault.
