A zookeeper has been killed in Britain after a tiger entered the enclosure she was in.
Visitors were evacuated from Hamerton Zoo Park in Huntingdon, Cambridgeshire, this morning.
Police were called to the attraction at 11.15am to reports of a serious incident, while a Magpas air ambulance was on the scene 20 minutes later.
Cambridgeshire Constabulary said on Facebook: "Officers attended a serious incident at Hamerton Zoo Park, Steeple Girding, at around 11.15am today.
"A tiger had entered an enclosure with a keeper. Sadly the female zookeeper died at the scene.
"At no time did the animal escape from the enclosure."
Hamerton Zoo Park has said that a "freak accident" is to blame for the incident.
It said: "Our thoughts and sympathies are with our colleagues, friends and families at this dreadful time".
The zoo confirmed it would remain closed tomorrow while the investigation continues.
In 2008 Hamerton Zoo Park hit the headlines after a nine-year-old Cambridgeshire boy encountered an escaped cheetah in his back garden.
The hand-reared animal was thought to have escaped through a faulty electric fence, which was later replaced.
Four years ago, Sarah McClay died after being mauled by a Sumatran tiger at South Lakes Safari Zoo in Cumbria.
The zoo was fined £255,000 at Preston Crown Court in June last year following the 24-year-old employee's death in May 2013.
It received an additional £42,500 fine after it also pleaded guilty to other health and safety law breaches when a zookeeper fell from a ladder while preparing to feed big cats in July 2014.
Last October ZSL London Zoo was put on lockdown after Kumbuka the silverback gorilla managed to exit his enclosure through two security doors that had been left unlocked by a keeper.
Armed police were called to the central London attraction and visitors were evacuated when the alarm was raised on 13 October.
