Nepal's wildlife protection authorities have succeeded in controlling a tiger-eating human wild tiger believed to have killed a 71-year-old man outside a protected area in southwest Nepal.

Ashok Bhandari, director of Bardiya National Park, said on Monday that a team of 30 people, including forest rangers and security forces, had been deployed in the park, with four elephants being used to track down the accused tiger.

"We hit the tiger with a narcotic shot, and we took him to our rescue center," Ashok told Deutsche Presse-Agentur dpa.

The wild animal, believed to be a 15-year-old female, pounced on the elderly man on Sunday when he was feeding pigs outside his home near the park, and the search began soon after.

Bhandari said it was highly unlikely that the female pupils would be returned to the wild. He said: "Alberr in very bad condition."

He added that the rare animal may have had to migrate from his home after losing a battle on the ground with a tiger younger and more powerful.

It will be kept inside the barn for a month, then a decision is made on whether to launch it or most likely, grant it to the zoo.

Nepal has 235 endangered wild tiger animals living in protected areas in the southern plains along the border with India.
