Graham outside Brighton magistrates court where she is on trial for wasting police time

A stripper who once lap danced for Simon Cowell on Britain's Got Talent assaulted a man on a stag night and falsely accused him of sexual assault, a court heard.

Kerri Graham, who appeared in the 2013 series of the TV talent show, clashed with the groom's brother-in-law after she was paid to perform for a group of men in Brighton.

The city's magistrates' court was told how the chaotic night unfolded in March this year after the group, including host Rakesh Pathak, hired Graham for the party.

Prosecutors described how Graham was refused permission to strip in a bar the men were drinking in, and was then rejected by a nearby nightclub.

She offered to perform for the groom in her car, which was parked nearby, but was told he was 'handcuffed to a dwarf' and they couldn't all squeeze into her Hyundai, the court heard.

Instead, the groom's brother-in-law Mr Pathak went to her car but her performance was interrupted by two security guards who flashed torches in the car window, magistrates were told.

The four engaged in 'banter' and Graham 'jiggled her breasts' as one of the guards told her: 'My partner's are bigger,' the court heard.

But the stripper and her customer were told to move on and, after a short drive away from the car park, got into an argument when she refused to continue her performance, the court heard.

Mr Pathak claims she refused to return his money and threatened to say he had raped her when he grabbed her bag to look for it.

The court heard he took her bag 'to bargain' with her and ripped the rear windscreen wiper from her car.

Mr Pathak claims Graham struck him on the forehead while holding her phone, leaving him with a cut, and a picture of his wound was shown to the jury.

Graham then made a 999 call, which was played to the court, in which she said she was 'being attacked'. Mr Pathak can be heard in the background saying 'no you're f****** not'.

Mr Pathak then left, but was later arrested at a bar called Vodka Revolution on suspicion of assault, sexual assault and criminal damage, the court heard.

He later admitted criminal damage and paid a fixed penalty notice, and received no further action for the other alleged offences.

Graham denied assaulting a client when she took the stand at the trial.

In her police statement, Graham told officers Mr Pathak had followed her to her car and they had met in a club.

She said she did not want to tell officers her job at the time because she was embarrassed.

When prosecutor Ayisha Robertson put the inconsistencies to Graham, she said it was because she was traumatised and shocked by what had happened.

Graham told Ms Robertson: 'You're evil. You guys should be representing me. You know in your heart that you should be representing me. This has been nine months of hell for me.'

The court heard Graham claimed Mr Pathak assaulted her by punching her in the face twice after a row. She said he tried to get his money back when she said his time was up.

Graham claimed he stole her bag and taunted her as she tried to get it back and at one point twisted her arm when she got hold of it.

Graham, 48, of Thurrock, Essex, denies assault and wasting police time.

The trial continues.
