A toxic pesticide that a U.N. agency wanted India to ban a decade ago contaminated food that killed at least 15 people at a temple last week, police said on Tuesday.

More than 100 also had to go to hospital after devotees consumed portions of tomato rice blessed at the Hindu temple in the southern Indian state of Karnataka.

A senior police officer told Reuters laboratory tests showed the presence of monocrotophos — a pesticide that attacks the nerves — in food and vomit samples.
