Sheikh Mohsin, 35, grabbed the 45,000-rupee ($1,115) necklace from a woman in the eastern city of Kolkata Friday and popped it into his mouth when cornered by police.
Officers then fed him 40 bananas over a few hours believing they would act as a purgative, and sat back and waited for results.
Mohsin passed an uncomfortable night in jail, but not the piece of jewelry.
Forty bananas and still not passing it? Sheesh, what does this guy have, an iron stomach?
Dozens of bananas failed to do the trick but an Indian thief has finally produced a gold necklace he had snatched and then swallowed after police fed him a hearty meal of chicken, rice and local bread.
Ah, that does it. Well, that'll probably be the last decent meal he gets for a while: he's facing 3 years jail time now that the police actually have their evidence.
