NEW DELHI: A white tiger on Tuesday attacked and killed a schoolboy who appeared to have jumped or fallen into its enclosure at the zoo in the Indian capital, witnesses said. “The boy seems to have leapt over the railing into the tiger enclosure. It was a white tiger that attacked,” zoo manager Riaz Khan told Agence France-Presse. “We are trying to find out who this boy was and why he did what he did. The police are here and they are investigating,” he said.
