A white tiger at the New Delhi Zoo has attacked and killed a young man inside the tiger enclosure.There are mixed reports as to whether the young man jumped, or has accidentally fallen into the enclosure, and even the age of the individual. However, the most credible reports indicate the young man was an Indian student who slipped while taking photo's.National Zoological Park spokesman Riyaz Ahmed Khan said the man ignored repeated warnings that he should not get too close to the outdoor enclosure and climbed over a knee-high fence and small hedges.Authorities eventually frightened the tiger into a small cage inside the enclosure. Police arrived on the scene "very quickly", but could not save his life. The man, whose body remained in the outdoor enclosure two hours after the attack, was dead by the time help reached him, Mr Khan said.Deputy Commissioner of Police M.S. Randhawa identified the man only as Maqsood and said he was thought to be about 20 years old.
