A man was left seriously wounded after climbing into a bear enclosure in a Swiss zoo yesterday. The 25-year-man climbed onto a wall surrounding the BärenPark (Bear Park) in the city of Bern, Switzerland, before falling 13ft into the enclosure, police said. The unnamed man, who had learning difficulties, was then attacked by four-year-old bear Finn, who caused severe injuries to the man's head and one of his legs, before a nearby policeman shot the creature - injuring it and forcing it to retreat into a cave.
