A wild tiger cub attacked by villagers has died in a central Indian zoo two days after vets tried to save it with a rare blood transfusion, officials say, reported BBC.
The cub, Juhi, initially showed signs of improvement but suddenly went into convulsions and died, officials said.
Another cub found at the same time near the city of Nagpur in the state of Maharashtra is getting better and responding to treatment.
Loss of habitat has brought tigers into conflict with humans in India.
The blood transfusion is believed to be the first carried out on a tiger in India and was done after its haemoglobin dropped to "dangerously low" levels.
The seven-month-old cub was named Juhi after a fragrant white flower native to India.
'Several complications'
"The two cubs were found last week near Chandrapur [a forest area]," the chief wildlife officer in Nagpur, Bimal Majumdar, told the BBC.
"Both of them were very weak and hungry and were brought to Nagpur for treatment.
"One of them was given a blood transfusion. There were several complications, including external infections and damage to intestines."
A team of vets worked for over two days to save the cub - which was given blood from a tiger held in captivity near Mumbai (Bombay).
Mr Majumdar said that the death of the cub was a "sad moment".
"We have lost the battle," he told the Associated Press news agency. "She got convulsions this morning [Tuesday] and we tried our best to save her.
"But she stopped breathing and that's how the end came."
Juhi and her sister Jai, or Victory, were found near the Tadoba tiger reserve as they were being chased by villagers who wanted to kill them because they feared the animals would attack children and cattle.
Officials say that Jai is better and responding to treatment.
Experts say that there are only about 1,500 tigers in the wild in India - down from about 3,600 six years ago and an estimated 100,000 a century ago.
Human encroachment on their habitats, poaching and busy roads and railways have all been blamed for their demise.
