Three people are police custody in Ethiopia after they were arrested on suspicion of killing a South Sudanese university student in the town of Bishoftu last week.

Pur Reath Puok, a relative of the deceased, told Radio Tamazuj on Thursday that the Ethiopian police managed to arrest three people accused of killing Bil Puok Chuol.

He pointed out that Bil, 18, was returning from college when he was attacked by a group of criminals outside a shop on his way home.
