A 16-year-old girl, the last of the accused in the Greenock torture trial, was sentenced to 11 years yesterday.

Louise Campbell was a member of the six-strong gang who subjected a young woman to a sickening catalogue of cruelty.

The 21-year-old victim, Miss X, was beaten up, burned and stabbed so horrendously that a doctor compared her to a torture victim from a Bosnian Serb concentration camp.

The trial at the High Court in Glasgow heard how the gang laughed and joked as they tortured and humiliated their victim and told her that, ultimately, she would be put to death.

The court was told that the two-day orgy of torture began because Miss X owed one of her captors #40. Her ordeal ended when she managed to crawl out of a window to safety.

She was in hospital for three weeks and needed plastic surgery to treat the scald burns which covered large part of her upper body and arms.

She will need further plastic surgery and she told the court that not a day passes without her suffering nightmares.

Temporary judge John Horsburgh, QC, described the crimes as ``barbaric, disgusting and abhorrent''.

Campbell's boyfriend, Kenneth Woods, 27, of Banff Road, Greenock, was jailed for 16 years; Joanne McCulloch, 19, of Easter Drive, Portlethen, Aberdeen, and Julie Duffy, 17, of Cambridge Road, Greenock, were both ordered to be detained for 12 years.

A 15-year-old girl, who cannot be named for legal reasons, was sentenced to eight years.

They were all convicted of attempting to murder Miss X in the flat in Banff Road, Greenock, shortly before Christmas last year.

Another accused, Marie Davis, 19, of Burns Road, Greenock, was sentenced to two years after she admitted abducting and assaulting Miss X.

Mr Horsburgh deferred sentence on Campbell until yesterday for background reports.

At the High Court in Edinburgh, Mr Alastair Campbell QC, defence counsel, said that his client was now remorseful about what she had done.

Plainly, it was a serious matter and a lengthy sentence of detention was inevitable. Mr Campbell asked the judge to take his client's age into account.

Mr Horsburgh told the accused he had given careful consideration to her involvement in this case and could take her age into account.

``On the other hand account has to be taken of the fact that, on the evidence, your involvement was of a very material nature and that fact has to be reflected in the sentence.''
