A man has died after being attacked by a tiger after jumping into its enclosure at a zoo in Yorkshire, police have said.

Yorkshire Wildlife Park was evacuated shortly after the incident and the site will remain closed on Sunday.

South Yorkshire police said that at 1.35pm it received reports of an individual entering the enclosure at the zoo near Doncaster.

The force said the attack “resulted in serious injury”.

The statement added: “Emergency services attended and sadly, despite the best efforts of medical personnel, the man was pronounced dead at the scene.

“The man’s family is aware and is being supported by specialist officers. Our thoughts are with them at this distressing time.

“Regarding rumours surrounding the condition of the tiger, the animal was uninjured and remained in the enclosure following the incident and there is no wider risk to the public.”

The force earlier said: “We are aware of videos circulating online and we would encourage people not to share this distressing footage.”

Yorkshire Wildlife Park said a “serious incident” occurred inside the enclosure.

It said in a statement: “Our emergency response procedures were immediately activated, and emergency services are currently attending the scene.

“We are working closely with the authorities to ascertain exactly what happened.” It added that the “safety and wellbeing of visitors, staff and animals remain our highest priority”.

Footage shared on social media appeared to show a man wearing a black jumper sitting on the ground of the enclosure and being attacked by a tiger.

A Yorkshire ambulance service spokesperson said it sent a number of resources to the scene including two ambulances, Yorkshire air ambulance and a doctor.
