A man has been arrested by police authorities in Kuacjok town in South Sudan’s Gogrial state for killing a 45-year-old man whom he wrongly injected earlier this month, a senior police officer said.

Police inspector Santino Aleu said the man whose identify remains unknown was a primary school teacher before he started working as a pharmacist in one of the pharmacies owned by a certain payam administrator.

He urged the families of the victim to be patient as police authorities carry out their investigations into the incident.
