Police in Liberia are investigating two officers after they shot at people protesting against ritual killings in Kingsville, about 20km (12 miles) kilometres south of the capital, Monrovia, leaving at least one boy with serious injuries.
The boy was sitting by the roadside roasting and selling corns when he was shot in the head, residents said.
He is currently receiving treatment but his condition is said to be critical.
Local media reported three people were shot at and one died following Monday’s incident.
Another protester sustained a severe wound in his leg.
Police spokesman Moses Carter said the two officers had been hit with stones by the protesters before the shooting happened.
“Our concentration is on investigating our officers [who were involved in the shooting] because under the law they have to shoot only when their lives are under threat.”
“If it is found out their lives were never under any threat but they shot, then there is no justification for their action … we will take a step to serve as a deterrent for others,” he said.
Killings for ritual purposes are common in Liberia. Some body parts are believed to be useful in preparing charms for gaining political power and luck.
