"He then tried to antagonise the tigers by pulling faces at them. Eventually he was attacked by the male where he was cut after being scratched and bitten before he could be rescued by zoo keepers who fired a tranquilliser dart at the male tiger."
According to the Chengdu Business Daily, around 50 staff members responded in line with emergency protocol, first using a water hose to shock the male tiger into dropping Mr Yang, before tranquillising both male and female tigers.
Before keepers were able to enter the enclosure and retrieve him, Mr Yang reportedly retreated to the glass viewing panel at the front of the cage and started daubing it with pinkish-red ink.
Mr Yang was treated at the 416 Hospital in Chengdu for around a dozen light puncture wounds, and upon his release told reporters he had "wanted to feed the tigers". His backpack was found to be filled with brown rice, but local media agencies quoted family-members saying he had been suffering mental health problems recently and would now be taken for counselling.
Zoo keepers said Mr Yang had been extremely lucky to survive the ordeal. The white Bengal tigers were described as more docile because they have been bred from captivity, and had also only just finished a large meal.
They also inhabit a cage directly adjacent to a much more dominant, larger Siberian tiger, naturally making their behaviour more subdued. One keeper added that the outcome would have been very different if Mr Yang had chosen to enter the other enclosure.
