A HELENSBURGH charity shop manager who raped a teenage girl with learning difficulties faces a further wait to be sentenced.

Dad-of-three David Wernham, also known as David Collins, was due to find out his fate last week after he admitted raping the 13-year-old, making her pose naked and wear handcuffs, and taking hundreds of pictures of her in sexually explicit poses.

But the High Court in Dunfermline was told that sentence could not be passed because a social work report on the 51-year-old was not available.

A previous hearing at the High Court in Glasgow was told Wernham had met the girl at the charity shop where he worked and offered to take her on metal detection outings.

But instead he took her to his West Argyle Street home and sexually abused her.

He gave the girl, who has significant learning difficulties, gifts including toys, teddy bears, a pair of Nike shoes and other items.

When police raided Wernham's house they found a folder on his computer containing 565 indecent images of the girl, 219 of them showing her face, and a further 311 indecent images of children.

Wernham's face did not appear in any of the sickening pictures of the girl, but police were able to identify him because of his distinctive tattoos.

That hearing, in May, was told that Wernham's victim was “highly vulnerable” and incapable of giving consent to sex.

Prosecutor Stephen Borthwick said Wernham's crimes had come to light when the girl told a family member he had sexually abused her.

Wernham, who committed the offences between July 2015 and February 2016, initially claimed that the handcuffs used on the girl were toys and came from the 'dressing up' box at the shop he managed.

The images, found on a thumbnail cache holder on Wernham's computer, originally came from a USB stick which has never been found.

Wernham, who was remanded in custody after his guilty plea, will be brought back to the High Court in Glasgow for sentencing in August, when a plea in mitigation will be given by his defence team.

Judge Lord Beckett placed Wernham on the sex offenders' register at the May 25 hearing.
