Contaminated school lunch in India

The principal of a primary school in eastern India where 23 children died last week after eating lunch prepared with contaminated oil was arrested Wednesday, nine days after she went into hiding, police said.

Meena Kumari fled as soon as the children began falling ill after eating the lunch cooked at the school in Bihar state. Twenty-three children between the ages of 5 and 12 died after eating the meal and many others fell ill.

Forensic tests have revealed that the lunch contained toxic levels of a deadly pesticide. (AP)
