In a precedent not seen in Stockholm's Skansen open-air aquarium in 40 years, a man in his 70s was exposed to a crocodile bite in his arm that was taken to hospital, according to the BBC.
"The man accidentally inserted his arm into the protective glass where the crocodile is located," police chief Michael Peterson said in Stockholm.
The crocodile arrived in the Skansen basin in 1981 from Moscow with another crocodile. They were presented by the late Cuban leader Fidel Castro as a gift to Russian cosmonaut Vladimir Shatalov, who was visiting Cuba in 1978.
After a while, the Russian astronaut donated crocodiles to the Moscow Zoo when it became too big and dangerous. In 1981, they were donated by the head of the park, Vladimir Spitzen, to the Skansen Aquarium in Stockholm and handed them over.
