The mother of a Scottish zookeeper who was mauled to death by a tiger has demanded tougher rules to protect staff from dangerous animals.

Fiona McClay's daughter Sarah was killed when a tiger pounced on her in a zoo in Cumbria in May 2013.

She the latest death in Cambridgeshire this week should be a "wake-up call," with government intervention required to ensure safety.

On Monday, 33-year-old Rosa King was fatally attacked by a tiger at Hamerton Zoo Park.

A police investigation into her death is ongoing.

Mrs McClay, from Linlithgow in West Lothian, said: "First of all I thought for the the parents and colleagues of the person that's been killed, and then I thought that's really why I need to continue and campaign for changes in the legislation.

"The boxes people need to tick to run an establishment with category one animals have got to be stricter."

Sarah was attacked after a door-closing mechanism, which should have separated her from the animal, failed.

The 24-year-old keeper had initially been blamed for her death.

Her mother said: "There needs to be different rules regarding the design of the buildings these animals are housed in.

"If a door has a proper closure system then there shouldn't be an accident."

Regulation of zoos is currently overseen by local authorities but Mrs McClay said it should instead be handled by a separate body.

She said: "It needs to be looked at by a central body who has no interest in any facility staying open and any profit or any tourist effect that the facility has on the surrounding area.

"It needs to be tougher."
