The young man who was mauled to death by a tiger at a British wildlife park was identified Tuesday — as it emerged he filmed his own footage as he climbed into the big cat’s enclosure.

William Chapman, a “vulnerable” man in his early 20s, came alone to Yorkshire Wildlife Park in northern England on Saturday, according to police.

He then recorded shocking footage from inside the 420-pound predator’s enclosure moments before he was mauled to death, the Sun reported.

Another visitor said Chapman was “dancing erratically” earlier in the day before reportedly climbing into the tiger’s enclosure despite other visitors’ desperate attempts to pull him back.
