A "sexual predator" has been warned to prepare himself for a long prison sentence after he was convicted on Thursday of historical sex attacks against three women - one of them while he was working at a children's home in the 1980s.

Defendant John Clifford Davies, now aged 61, was a care worker at The South Meadows Care Home at Prestatyn, Mold Crown Court heard.

A judge said it was a feature of the case sadly that one of the complainants was not properly believed when she complained previously.

"That wrong has now been put right," said Judge Rowlands.

He denied raping a girl in care and two other females when they were young but was convicted by a jury at Mold Crown Court on Thursday afternoon.

Davies, of Abergele Road in Colwyn Bay, convicted of raping the girl in care between May and September 1986.

He was convicted of two charges of rape, three charges of indecent assault and two charges of indecency with a child against a girl under the age of 11 in the 1970s.

And he was convicted of one rape and two charges of sexual assault against another woman when she was a teenage girl in 2007.

He was cleared of another charge of rape against her.

Davies denied all 12 charges and said the allegations against him were not true.

Following the convictions, Davies' bail was revoked and he was remanded in custody pending sentence on January 20.

Judge Rhys Rowland said that he had been convicted "on the most compelling evidence" of the most serious depravity.

They had been committed against three separate victims, one of them being extremely young at the time.

The judge ordered victim impact statements to be prepared for the next hearing.

"I do not know the true effects of this on the victims. I can guess.

"But there will be victim impact statements when you return to be sentenced."

Judge Rowlands said that a feature of the case sadly was that one of the complainants had not been properly believed by those who investigated the case in the past.

"That wrong has now been put right," the judge said.

"You must prepare yourself for a very lengthy sentence when you return to court."

Davies must now register with the police as a sex offender for life.

While at the home, he befriended a vulnerable girl then aged 15 or 16 and would talk to her about her problems, alleged prosecuting barrister Danny Moore.

They would have long conversations late at night when other residents were asleep. It was the prosecution case that he was effectively grooming her.

They began to meet off site at local pubs.

He would occasionally buy her alcohol and she was flattered by the attention, the prosecutor said.

Davies, it was alleged, promised to take her to her mother's home.

He took her to his own home, it was claimed, and she was able to describe where he lived in some detail.

Davies said he would deliver her to her mother's home but on the way it was alleged he stopped in a secluded area.

Without saying anything, it was alleged that he adjusted the seats, kissed her against her will, took off her jeans and raped her.

She described it as crude and painful.

Later interviewed, she said that it was unwanted and she froze.

She said that at that stage "her body closed down and she went into shock."

Mr Moore said the defendant returned her to the home and she recalled some weeks later being called into a meeting to discuss inappropriate behaviour between the two of them.

Someone had seen them together in a pub and had reported it to the home.

There was something of an inquiry and on her way to the meeting it was alleged that Davies threatened her that she would be sent to an unpleasant care home if she revealed what had happened.

The prosecutor said that there was no record of the inquiry but the defendant had agreed there was one.

He said he had been told he had better resign following allegations about his relationship with the girl .

Davies told police that he did recall the girl at the home but said that he had acted perfectly properly towards her.

The defendant accused her of making up the allegation for compensation.

But material gathered by officers of The National Crime Agency under Operation Pallial showed that she had mentioned the allegation to a probation officer and to a friend previously, the prosecutor said.

The prosecution alleged that Davies was a sexual predator taking advantage of the complainants over the years.

They claim that he had a sexual interest in girls under the age of 15 and would abuse his position to create opportunities to be alone with the children and exploit them sexually.

Davies denies all the allegations and his barrister Duncan Bould said that it was the defence case that the acts alleged had simply not happened.
