The brother of a double murderer raped a student in her bed then issued a blood-curdling threat to her flatmates warning them to “Google me – see what I’m capable of”.

Floyd Clifton has been unanimously found guilty of attacking the 22-year-old after tagging along with her friends on a night out in Canterbury.

A jury heard how Clifton had a record dating back to 2000 for crimes including burglaries, robbery, witness intimidation, threats to kill and kidnapping.

They were told how, when arrested, the 29-year-old had joked to police officers: “Rape? That’s me going back to Elmley Prison then.”

Clifton had latched on to a group of young students who were enjoying a party in a city centre pub.

“I was really upset, crying and hysterical. I just wanted him out of my house,” she said. “He told us: ‘Google me, see what I am capable of’ ” - Clifton's victim

Deciding they were drunk, the group had hailed a taxi to head home – with Clifton jumping in with them.

Back at their flat Clifton helped carry the victim’s friend to bed before joining her in her own bedroom.

The jury was told Clifton, of Gordon Road, Canterbury, had left the room and the victim had fallen asleep.

“I woke up sometime later and he was on top of me. He was having sex with me,” she said. “I pushed him off me. I then jumped up and put some pyjama bottoms on. I started screaming.”

She alerted her fellow students and Clifton became defensive, claiming he had done nothing wrong.

“I was really upset, crying and hysterical. I just wanted him out of my house,” she said. “He told us: ‘Google me, see what I am capable of’ ”.

Clifton later admitted to the jury that he wanted the students to see stories of his brother Brett, 31, who is serving time for a double murder in Faversham nine years ago, to prove who he was.

The jury was told Clifton had a criminal record of 24 convictions dating back more than a decade.

He had denied the rape, claiming sex with his victim had been consensual.

He will be sentenced in October and was remanded in custody.

After the verdict was announced Judge James O’Mahony said: “I am completely sure that blood-curdling threats were made and it is perfectly clear to me that there is every reason to think that this defendant is extremely dangerous. He stalked these girls and laid in wait.”

Brett Clifton

Floyd’s brother Brett was sentenced to life in prison after he brutally murdered an elderly couple in 2006.

The judge had called him ‘callous, spineless and wicked’ as the jury of 10 men and two women took just over an hour to return guilty verdicts on the two murder charges.

Terry Martin, 72, and his wife Vera, 78, were ‘ferociously beaten’ and left for dead at their house in Abbey Street.

Brett, who was 22 at the time and living in Beckett Street in Faversham, had broken into their house on January 21 before launching a ‘sadistic and brutal attack’ on the couple.

During the case, where Brett had pleaded not guilty, the prosecution had pointed out that Mr Martin could have survived for up to 24 hours after the attack.

Nathan Clifton

Floyd’s younger brother Nathan was this year sentenced to two years in prison after admitting two burglaries and an assault by beating charge.

The 23-year-old, who lived in lived in Beckett Street for some time, broke into a house and stole car keys in Canute Road, Deal last year when house-owner spotted him sitting in the vehicle.

During a struggle, the owner's son was injured when Clifton tried to throttle him.
