A zookeeper who was mauled to death by a tiger was discovered by a visitor in the public viewing area who raised alarm to the incident.
Rosa King had been cleaning the windows of the tiger enclosure at Hamerton Zoo Park in Cambridgeshire when she was attacked by a Malayan male called Cicip.
An inquest at Huntingdon Town Hall today heard that she died at the scene on May 29 2017, after two gates and a metal vertical slide, which was in place to ensure staff were safe - was found to have been left open.
The 33-year-old had been working alone when she entered the enclosure shortly before it opened to the public at 10am.
Nicholas Moss, Cambridgeshire's assistant coroner said Cicip 'would tend to urinate on the windows during the day so they needed to be clean so the public could have a good view'.
Her body had been dragged to the far side of the enclosure before it was spotted by Frank York who had been visiting the zoo.
Seeing her body from the viewing area, her alarmed zoo keepers who fetched a tranquiliser gun, while armed firearms officers and paramedics attended.

The male Malayan tiger Cicip, pictured, killed Rosa in a 'freak accident' last year. Keepers were said to have been able to entice him back into the enclosure after the incident
Mr Moss told the jury: 'He went to get help and a number of colleagues responded to that emergency.
'The pubic were evacuated and the paramedics were called.
'The keepers who came to assist were able to coerce the tiger back into his run and the slide was closed behind him to make the area safe again.
'It was not necessary to shoot the tiger or put him down.'
Neither the tranquiliser nor police firearms were used.
On the day of the incident, Rosa was working alongside a work experience student called Lucy Tonkin between 9.15am and 9.35am until Rosa had to go
