A weapon obsessed prison guard who armed himself with “a rapist’s toolkit” before attacking a prostitute at gunpoint has been jailed.

Richard Scaife was carrying an imitation handgun, bayonet, pierced condom, expired HMP identification badge and gaffa tape, at the time of his arrest.

And officers would uncover strips of duct tape stuck to the inside of the 46-year-old’s jacket, after he twice raped the sex worker in Folkestone, on November 5 last year.

Judge Catherine Brown on Friday sentenced Scaife to 15 years at Canterbury Crown Court after he was convicted following a trial earlier this year.

A huge arsenal of weapons was discovered stockpiled at Scaife’s Dover home shortly after his arrest; six machetes, 14 lock-knives, a samurai sword, eight ball-bearing pistols and air rifles among the haul.

Scaife denied any wrongdoing but jurors unanimously convicted him of two counts of rape.

Scaife’s victim told jurors he locked the door and grabbed her by the throat after arriving at her property in the afternoon smelling of alcohol.

“He pulled out the gun, I was terrified, but I didn’t show him.

“Inside, I thought ‘I’m going to die, this is my last day.’

“‘Maybe he killed someone before’ - all of this (was going) through my mind,” she said in a police interview, played to jurors as evidence.

“I have known many working girls who have been killed, I said ‘are you going to kill me?’

“All that was going through my mind was ‘am I going to die.’

“I was thinking of my son, I was thinking ‘I love you,’ this is going to be my last day, then I thought I have to be strong,” she continued.

She told how she managed to diffuse Scaife’s rage by speaking with him calmly while plotting her escape.

Eventually, after declaring he had problems in his romantic life, Scaife would bizarrely go on to ask if she wanted to form a relationship, she explained.

“He said ‘I have been seeing working girls for 20 years, they just take my money, they rip me off, they take everything away from me,” she continued.

“He broke down, he kneeled on the floor crying and I was hugging him, I said ‘you can talk to me honey’, and he said he really wanted to be friends with me.

“I thought maybe he was going to kidnap me and use me as a sex-slave in his apartment.

“He said he wanted to do bad things, ‘I wanted to do bad, I was expecting a bad girl but you are not a bad girl.’ ”

She eventually managed to alert her landlord and convince Scaife to leave, as another customer was waiting outside - her phone repeatedly sounding off.

After she called 999 Scaife was soon arrested in the same street an hour later, equipped with his “rapist’s toolkit,” prosecutors explained.

“He had weapons both in his car and on his person, he had an expired prison guard’s identification badge.

“He had strips of duct tape ready and cut, stuck to the inside of his jacket, ready to place over the woman’s mouth if he needed to subdue her.

“He had a condom with a hole in it.

“He brought with him an air pistol which had the appearance of a handgun,” Daniel Stevenson explained.

“We say there is no good reason why he would have an identification card that resembles that of a police officer,” he continued.

Giving evidence, Scaife argued the duct tape was for “fixing the window of my car,” his victim was setting him up for unknown reasons and he had forgotten his expired prison ID was even inside his wallet.

He also told jurors he was en-route taking the air-gun and bayonet found inside his car to the nearby Folkestone Angling shop for a refund at the time of his arrest.

But the shop owner told the court it had not stocked either item for more than a decade, and they would not have provided a refund in any case.

Scaife claimed weapons police seized from his home were for legitimate purposes - airsoft and martial arts, for example.

They included:

Air rifles

8 BB pistols

2 X wooden cosh

6 X machetes

1 X samurai sword

9 X fixed blade knives,

6 X folding lock knives

2 X metal asps

2 X foam batons

1 X nunchucks

2 X knuckledusters

Scaife, of Camden Crescent, was unanimously convicted of two counts of rape, posessing an imitation firearm to cause fear of violence and carrying a bladed article.

He was ordered to serve an extended five years on licence following his release.

After sentencing, Det Sgt Dan Barker, of the Kent and Essex Serious Crime Directorate, said: "Scaife put this victim through a terrifying ordeal and - like the judge recognised in court - I would also like to praise her bravery in assisting our investigation and the resulting prosecution.

"Scaife’s actions and the weapons he had in his possession present a disturbing portrait of a man who posed a serious danger to women and girls.

"I am pleased the fast and professional response of officers on the day of the offences led to his quick arrest and the seizure of these weapons.

"Every woman and girl has a right to feel safe in the communities in which they live and that is why tackling violence against them is a priority for Kent Police."
