A 23-year-old drunk was fined £ 6,000 for entering a bear enclosure and wrestling without a mask.
The unidentified man jumped into the enclosure of ex-circus bear Sabrina at the Warsaw Zoo in Poland and started struggling with it.
The bizarre attack was witnessed by zoo visitors filming the entire incident while a second alerted authorities.
The footage shows the man entering the enclosure and approaching the bear before jumping into the water when Sabrina attacks him.
Sabrina then followed the man’s movements on the waterfront before stepping into the water herself and smiling at the man.
Then he attacked Sabrina and jumped onto her back, pulling her ears and wrapping his arms around her neck to flee.
Firemen arrived to rescue the man from the fence, and he was later arrested and charged with animal cruelty and without a face mask.
He was fined $ 300 (£ 245) for animal cruelty and peace disturbance and $ 7,000 (£ 5,728) for not wearing a face mask.
The man was also sentenced to 20 hours of community service and ordered to give up alcohol.
Sabrina is used to human encounters and accustomed to the presence of people, but did not expect a human attack.
The zoo said Sabrina the bear was sad and “insane,” but the man emerged unharmed during the unjustified attack.
In a statement, Warsaw Zoo said it supported the prosecution of Sabrina’s attacker.
The zoo said Sabrina’s “psychological comfort was disturbed during the attack.”
