The owner of the wildlife park where a woman was killed by a tiger has said he has no explanation as to why she entered the enclosure.
David Gill, owner and founder of South Lakes Wild Animal Park, told BBC Radio 5 Live: "After investigation by the authorities here and the police, it does seem that she just basically failed to follow the correct procedures ...
"All we know is that no one else was involved, there was nobody with her, and for some unknown reason she opened a door and walked straight into the tigers."
Sarah McClay had worked at the wildlife park for a number of years and was "very proficient" in her work with big cats, he said.
He added that it was against strict safety protocols to walk into the tiger's cage and that the zoo had passed a major inspection on Monday in which it was praised for its safety standards.
