A man has been attacked by a tiger after jumping into its enclosure at a zoo in Yorkshire.

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

South Yorkshire police said 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: “Officers are working at pace to make contact with the man’s family and no further detail will be provided at this time.

“The tiger remained in the enclosure following the incident and there is no wider risk to the public … Yorkshire Wildlife Park was evacuated and officers remain on scene carrying out inquiries.

“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.
