One tiger was shot dead after the visitor reportedly climbed into the enclosure and walked towards the animals as they were being fed. Horror footage shows the tigers leap on the man at Ningbo Younger Zoo, leaving him writhing around on the ground in agony as they passed him between their massive paws.
Reports from China say the man has died from his injuries.
Zoo keepers tried to frighten the animals away with firecrackers and water canons, but they were undeterred.
The animals then bit into his head and neck and ripped off his clothes, leaving him face down on the ground in just his pants.
One witness told the South China Morning Post : “I saw the tiger mauling the person, whose face was covered with blood. Every time he sat up, the tiger pushed him down again.”
Witnesses said he walked into an isolation zone shortly before 2.30pm local time (6.30am UK time) and crossed a river that separates the enclosure from visitors.
Shocked bystanders said the man was with his wife and child when he walked into the enclosure.
