A professional cricketer raped a sleeping woman after helping to set up a sexual conquest “game” with friends on WhatsApp, a court has heard.

Alex Hepburn, a Worcestershire CCC all-rounder, is alleged to have attacked the woman in a dark bedroom shortly after she had consensual sex with one of his teammates, Joe Clarke, after a night out.

Jurors heard the victim initially believed she was still in bed with Clarke, who had left the room to be sick, after waking up to find Australian-born Hepburn, 23, performing a sex act on her.

Opening the prosecution’s case, Miranda Moore QC said the alleged victim realised she was not with Clarke when she touched Hepburn’s hair and he spoke in an Australian accent.

Describing the aftermath of the alleged attack to the jury, Moore said: “Immediately she pulls away, she says: ‘Where’s Joe?’

“Hepburn says to her, ‘You are beautiful’ and tries to encourage her to continue having sex with him but she is having absolutely none of it.”

The woman, who cannot be identified, told Hepburn he was a “sick bastard” and phoned a friend to tell her about the alleged rape, the court heard.

Taking jurors through WhatsApp messages found on Hepburn’s mobile, Moore alleged that a “stat chat” group he took part in was set up to record details of women its members had slept with.

The court was told references had been made in the WhatsApp group to “freshies” and “re-heats”, alleged to relate to women its members had or had not slept with previously.

After taking the jury through “rules” posted on the group days before the alleged rape, Moore told the court: “From the prosecution point of view, it may well be that what was on this defendant’s phone will help you in deciding what he was up to that night.

“It detailed the game that these young men engaged in and intended to follow. This game had precious little to do with cricket.”

Among the rules was a request for “every freshie” to be “rated out of 10” and a stipulation that the “winner” be able to gloat and enjoy a free night out paid for by other members.

At the end of her opening address to the jury, Moore said of Hepburn: “The ‘score’ that he hoped to make may well help you in the explanation as to what he was doing to her. He saw that girl asleep in the bed and decided to take advantage.”

A police interview conducted with the alleged victim shortly after the offence was played to the jury during Monday’s evidence.

In the video, the woman told a police officer she had assumed she was having sex with Clarke, who was of a similar height and build, before “panic set in” when she saw Hepburn.

The prosecutor told Worcester crown court a member of the public dialled 999 in the early hours after finding the complainant “distressed and crying” in the street following the alleged attack in April 2017.

Hepburn, of Worcester, denies two counts of rape, claiming the alleged victim was awake and that initial kissing led to consensual sexual contact.

The trial continues.
