A zoo has admitted health and safety breaches over the death of a Scots keeper who was mauled by a tiger.

Sarah McClay, 24, was pounced on in the keeper's corridor of the tiger house at South Lakes Wild Animal Park in Cumbria.

The owners of the zoo pleaded guilty to failing to ensure the health, safety and welfare of Ms McClay in relation to the Sumatran tiger attack on May 24, 2013.

Ms McClay, originally from Glasgow, suffered "unsurvivable" injuries before she was airlifted to hospital, where she was formally pronounced dead.

At Preston Crown Court on Wednesday, the park owners also admitted failing to ensure that people not employed by the park were not exposed to risk to their health and safety.

The pleas were entered ahead of trial, while sentencing will take place on Friday.

Following the hearing, Ms McClay's boyfriend, David Shaw, said: "It's a shame it took this long to come to what was a fairly obvious conclusion but I am pleased we do not have to go through a trial."

In September 2014, an inquest jury in Kendal ruled in a narrative verdict that Padang the Sumatran tiger got to Miss McClay by entering two open internal sliding gates within the tiger house and then an open door that led on to the corridor.

Systems were in place at the park to ensure that animals and keepers remained apart at all times through indoor and outdoor compartments connected by lockable self-closing doors, the inquest heard.

Ms McClay had worked at the park for more than two years and was well experienced with working with big cats which she saw as a "privilege".

Her mother Fiona McClay, from Linlithgow, West Lothian, said it was her daughter's "dream job" after she had visited the park as a child.
