Ugandan police are investigating the suspected poisoning deaths of four pupils at a school in Kampala, after the head teacher was arrested to assist with the probe.
The four girls, aged 9 and 11, died Tuesday. Three died at home and the fourth died after emergency treatment at a hospital. Eight pupils ate oranges shared by a fellow pupil, and five pupils, including the four who died, began vomiting. Post-mortem examinations are being carried out to determine the exact cause of death.
