THE husband of a rape victim has slammed the Crown Prosecution Service for failing to take action after he was allegedly threatened in court by the rapist's brother.

The husband, who is in his 60s, spoke to the Free Press of his disgust at the decision by the Aylesbury Crown Prosecution Service not to pursue any action against Mark Archibald following claims he made a threat.

The CPS said there was not enough evidence for a conviction for witness intimidation and it was not in the public interest to pursue the case further.

The husband of the rape victim is a BBC TV news presenter who cannot be named for legal reasons. He claims that Mark Archibald, 27, issued a threat after his brother John Archibald was sentenced to jail for three years for the "unbelievably wicked and disgusting" rape, at Reading Crown Court.

John Archibald, of Wapseys Wood caravan site, in Gerrards Cross, had been found guilty at the court in April of raping the presenter's dying wife in a South Buckinghamshire nursing home.

And now the victim's husband says he is furious no action will be taken following the alleged threat that he says was made in front of court officials, police and several journalists.

He said his home had to be fitted by police with emergency alarms and CCTV cameras following the court case.

He added: "For the past three months the family have had to endure siege-like conditions. We've been advised to be vigilant at all times.

"I was shocked the police didn't arrest him on the spot. Now I've been officially informed the CPS is not to press charges.

"They've accepted his explanation that what he said was a misunderstanding."

Following the court case, police investigated the alleged threat and statements were taken from those who witnessed the incident.

And a spokesman for Aylesbury CPS admitted: "We did have enough evidence to support a minor public order offence under Section 5 of the Public Order Act 1986 but it was not in the public interest to pursue it."

She added: "There was not enough evidence for a realistic prospect of conviction for the offence of witness intimidation."

Chris Albin, of Griffiths Robertson Solicitors, who represented Mark Archibald, said his client would not have a comment to make.

However, in relation to any allegation of witness intimidation, Mr Albin added: "There was a doubt as to whether [the husband] was a witness in the first place."

John Archibald is appealing against his rape conviction but the Attorney General has lodged a counter appeal, claiming the three-year sentence was too lenient.
