City of Doncaster Council, which licenses the park, said on Monday it had started a health and safety investigation.
Dan Swaine, executive director of place at City of Doncaster Council, said: “As the relevant licensing authority for the Yorkshire Wildlife Park, I can confirm that, in line with our statutory duties, the council has launched a health and safety investigation.
“We are also working with multiple agencies, including the police and health agencies, and are supporting the Yorkshire Wildlife Park in response to the incident.
“At this time, we won’t be commenting further on the individual or the investigation and we ask that the privacy of those involved is respected at this difficult time.”
In a previous social media statement, the wildlife park said “many, many people” had contacted them about Altai, the Amur tiger involved in the incident, and confirmed he is “safe and well” and will not be euthanised.
