Around 500 people in east Delhi were admitted to a hospital with complaints of stomach ache, diarrhoea and vomiting after reportedly consuming adulterated 'kuttu ka atta' (buckwheat), eaten during the Navratras, police said.

The incident was reported late Tuesday night. Those who have been admitted to the Lal Bahadur Shastri Hospital hail from Kalyanpuri, Trilokpuri and Khichdipur and other nearby residential colonies.
