The death of 24-year-old William Chapman after he entered the tiger enclosure at Yorkshire Wildlife Park has left investigators, his family, and the public seeking to understand the sequence of decisions that led to the fatal encounter with Altai. Chapman, who had been diagnosed with schizophrenia and had experienced previous bouts of psychosis, was living independently in Doncaster and working as a self-employed online trader. He was under the care of local mental health services but ᴀssessed as highly functioning with no care requirements. On 10 October he visited the park alone, was observed pacing near the enclosure with headphones in, and then climbed two fences before moving toward the tiger. Eyewitnesses described attempts by visitors and staff to intervene, including shouting, banging on barriers, and the use of air sH๏τs, yet the interaction escalated quickly.

The inquest opening confirmed that the resulting injuries were multiple and traumatic and that death followed rapidly. His family has publicly expressed concerns about his contact with mental health services in the lead-up to the incident and has asked for privacy while investigations proceed. They described him as bright, warm and engaging, noted that he had been prescribed strong medication for significant mental illness over a number of years, and said they hoped authorities would determine why he acted as he did. Parallel inquiries by the NHS trust, Doncaster Council, and police are examining his care, the enclosure’s security arrangements, and the events of that afternoon. With the full inquest not due until March 2027, the case continues to highlight the challenges of supporting people who live independently with serious mental health conditions and the practical questions that arise when such a tragedy occurs in a public space.

William Chapman’s own mobile phone footage, captured from inside the tiger enclosure at Yorkshire Wildlife Park, has become one of the most closely examined pieces of evidence in the investigation into his death. The short clip shows him walking across open grᴀss toward Altai, the large Amur tiger resting on a wooden platform several metres ahead. Investigators and the public have studied the footage for clues about his state of mind in those last moments. Eyewitnesses on the raised walkway said he appeared to move deliberately rather than in panic, with some describing him as seeming disconnected or in a trance-like state before the tiger approached. One visitor recalled him crawling forward and lying down in front of the animal. Park staff reacted within seconds, using air sH๏τs in an attempt to distract Altai, yet the physical contact that followed proved fatal.

The inquest opening on 15 October confirmed that the interaction resulted in multiple traumatic injuries that rapidly led to death. Chapman, 24, had visited the park alone that Saturday afternoon after being observed pacing near the barrier with headphones in. The existence of the self-recorded video has intensified questions about whether he intended to enter the enclosure and what role his documented history of schizophrenia and previous psycH๏τic episodes may have played. His family has asked people to stop circulating distressing material, saying the content has caused them severe additional distress. Police, the coroner, and the council continue to gather evidence, including any CCTV from the park, ahead of the full inquest scheduled for 18 March 2027. The footage remains central to understanding the precise sequence that unfolded in full view of other visitors.
