A foster carer who abused children in her care has been released from prison after her sentence was reduced on appeal.

Barbara Daniel and her husband Douglas were found guilty in January of abusing six foster children - aged between four and 14 - at their home in Glasgow's Parkhead between 1986 and 1991.

The 76-year-old was jailed for two-and-a-half years in March, but her successful appeal saw it cut to just over five months.

Her eligibility for release was set at 81 days, meaning Daniel was free to go given the time she has already spent in custody.

A solicitor representing the abuse survivors said they were "deeply disappointed and angry" over the decision.

Glasgow Sheriff Court previously heard the couple - who fostered about 100 children - forced some of them into an animal pen, ordered one to bathe in a bird bath and made another eat a cow's tongue.

They were both jailed for 30 months in March.

But Barbara Daniel lodged an appeal on the ground of her health and age.

On Tuesday, at the Sheriff Appeal Court in Edinburgh, the original sentence was quashed.

A substitute sentence of 162 days - roughly five-and-a-half months backdated to 9 March - was put in place.

Rhona Phillips is a solicitor with the Irwin Mitchell Scotland law firm which represents survivors currently taking civil action against Glasgow City Council.

She said the victims were unhappy with the decision.

Phillips added: "It was acknowledged that Barbara Daniel's conduct caused significant harm to her victims - however this is of little comfort to survivors of abuse at her hands given the significant reduction in her sentence.

"Her counsel highlighted health concerns due to her advanced age, however throughout the criminal trial the survivors I spoke with said there was no regard shown to their own age and vulnerabilities at the time of offending, so they are deeply disappointed and angry about this decision."

Daniel and her husband had denied all the charges.

However they were found unanimously guilty of six charges of cruel and unnatural treatment of a child in January.

Sheriff Louise Arrol told the couple they had been convicted of "unspeakable abuse".

She said their home was meant to be a place of sanctuary for children in their care, but instead had become "nothing short of a house of horrors".

The court heard one young girl, who had a fear of chickens, was locked inside a chicken coop.

Another victim said she was forced to stand outside with a gaggle of geese who would nip at her skin and cause red marks which "would not go away".

Some of the victims told jurors that they were not fed by the Daniels while one claimed she ate from the kitchen floor.

A 47-year-old man who stayed with the couple told jurors that Barbara was seen as the "boss" while retired car mechanic Douglas was described as a "scary physical man."

It was later revealed that Douglas Daniel had 26 convictions - including for housebreaking and car theft - when he and his wife began fostering children.
