The opening of an inquest into the death of William Chapman, 24, heard that he died of "multiple traumatic injuries and animal interaction" after entering the tiger enclosure at Yorkshire Wildlife Park near Doncaster.
The hearing was told that Mr Chapman climbed two fences to enter the enclosure on Saturday. The incident took place shortly after 13:30 BST and led to the evacuation of the park. The park remains closed, and no reopening date has been confirmed.
Senior coroner Nicola Mundy opened proceedings at Doncaster Coroner's Court on Thursday. She said Mr Chapman had a history of mental illness, a diagnosis of schizophrenia and had suffered previous bouts of psychosis.
The court heard that his family had raised concerns about his treatment by Rotherham, Doncaster and South Humber NHS Trust. Mr Chapman's family chose not to attend the hearing. The inquest was adjourned until March 2027.
