A 43-year-old man tried to enter a tiger enclosure at Kamla Nehru Zoo in Madhya Pradesh's Indore city on Friday, and was saved by alert zoo officials.
Vijay Jhala climbed a 25-feet-high fence around the tiger enclosure, but was immediately brought down by alert zoo employees before he could enter it, zoo in-charge Uttam Yadav said.
Two tigers and a tigress were present in the enclosure at the time, he said.
On interrogation, Vijay Jhala claimed that he was severely debt-ridden and wanted to kill himself, Mr Yadav said.
He was later handed over to police and further investigations are underway, a police official said.
Vijay Jhala seems mentally unsound and may have been under the influence of drugs, police added.
