Two violent rapists could be jailed for up to 15 years after being convicted of battering, raping and falsely imprisoning two women.

Cousins Corrie Pinney, 35, from Yarbridge Close, Belmont, and Jermaine Kraftner, 27, from Poole, in Dorset, were found guilty of 14 charges against the two women in separate attacks in July 2009 and April 2010.

A third defendant, Cassie Webb, 21, from Croydon, was also accused of filming and aiding and abetting the second woman’s rape ordeal, but the jury was unable to come to majority verdict.

Webb, who was found guilty of aiding and abetting assault, could still face the possibility of a retrial on the remaining four offences, if the Crown Prosecution Service (CPS) decides it could result in a conviction.

Both attacks had striking similarities, including taking place at Pinney’s flat, the use of a speaker to block the front door and the involvement of both defendants.

The first attack happened on July 29, 2009, when Pinney lured a 17-year-old to his flat after a date.

But the football coach then raped her with his flatmate when she refused sex. In a horrifying twist, Kraftner’s father [Desmond Enwright] was said to have joined in after he wandered into the room.

The second attack took place on April 20, 2010, when an evening of cannabis smoking and drinking alcohol turned into a “degrading and humiliating” ordeal, where the 22-year-old woman was tortured and threatened with sadistic violence.

Hanna Llewellyn-Waters, prosecting, told the jury Webb filmed the sexual and physical abuse on a mobile phone, as the victim was put through a horrific five-hour ordeal.

If the victim disobeyed them the defendants repeatedly kicked and punched her and said they would cut off her hair, pour boiling water on her or stab her with a samurai sword.

Miss Llewellyn-Waters said: “The attacks were designed to degrade and instill terror in the women for the sense of power and sexual gratification of the two male defendants.

“Both [cases] involved sexual degradation, humiliation and a third-party and both victims sustained injuries of varying degrees.”

Pinney and Kraftner were convicted of four counts of rape, two counts of false imprisonment and two counts of sexual assault.

At the start of the trial both men, who will be sentenced on at Croydon Crown Court on August 1, had admitted assaulting the second victim.
