Jemma Beale is on trial for four counts of perjury and four counts of perverting the course of justice over false rape claims

A woman's false claims she had been sexually assaulted by up to 15 attackers in three years led to one man being jailed for seven years, a court has heard.

Jemma Beale, 25, twice told juries Mahan Cassim raped her after giving her a lift home in November 2010.

Beale said she was a lesbian with 'no desire' to have sex with men and Mr Cassim was jailed for seven years following a retrial at Isleworth Crown Court in January 2012.

Beale then told police she was groped by stranger Noam Shazad in a pub in July 2011 and he then took part in a gang rape attack involving 'sexual violence of a most serious kind'.

Mr Shazad skipped bail and fled the country after being charged with sexual assault, the court heard.

Beale then made two bogus complaints against six other men in 2013, Southwark Crown Court was told.

She claimed two strangers sexually assaulted her close to her home in Ashford, Middlesex, before she was put through another gang rape attack by four other men two months later.

Two of those identified by Beale as being involved in the last attack were arrested and interviewed in connection with the assault but never charged, jurors heard.

Beale now denies four counts of perjury and four of perverting the course of justice.

The charges relate to accounts she gave at Mr Cassim's trials along with the four complaints she made to police about the other attacks between 2010 and 2013.

John Price, QC, prosecuting, said: 'Ms Beale maintains that in a period of around three years, on four different and wholly unconnected occasions, one of which involved two attacks and two of which - a year apart - involved the same unknown man, she has been seriously sexually assaulted by six men and raped by nine - all bar one of whom on the day of the alleged incident were strangers to her.

'The prosecution ask rhetorically, is this in itself not inherently improbable?'

Beale then complained to police she was the victim of two more sexual assaults in 2012 and 2013.

She claimed she was groped inside a pub in Hounslow, then attacked in an alleyway close to the car park of a nearby medical centre.

'In that case she told the police she had been sexually assaulted by four men and she had recognised one of the four of them as being the same man who had assaulted her in the public house,' said the prosecutor.

A man named Noam Shazad was identified by police and he was arrested in 2012.

Beale claimed Mr Shazad, wearing a red baseball cap, molested her by grabbing her crotch inside the pub before attacking her again in the alleyway after being joined by three other men.

'The group of men did not exist,' said Mr Price, adding that the injuries she claimed to have suffered at their hands were 'self-inflicted'.

The prosecutor said: 'On Monday 2 September 2013, Ms Beale reported yet another serious sexual assault, this time by two men.

'She told the police that it had happened five days earlier, on Thursday 29 August, and she said it had happened outside of her home.

'Neither of those two men has ever been identified.'

Jurors heard that two months later, on 17 November, Beale reported another attack in Feltham, west London.

'She described a gang rape at night in a street of the most appalling kind,' said Mr Price.

Two men were arrested over that claim, but neither were charged.

The prosecutor added: 'It was as we submit - a grotesque invention... each of those reports made by Jemma Beale to the police is alleged by the prosecution in this case as being entirely false.

'She had not been raped. Nor had she been sexually assaulted on any of these occasions.

'Because of what she did, four men have subsequently suffered serious injustice - one of them of the gravest kind.'

Jurors heard that each of the men were questioned by police 'suspected of amongst the most serious of criminal offences' garnering 'public revulsion and notoriety'.

Beale, of Bedfont, Middlesex, denies four counts of perjury and four counts of perverting the course of justice. The trial continues.
