River in Ghana turns blood red overnight and nobody knows why

Residents of Koforidua in Ghana were left baffled when they woke up and discovered the waters of the Nsukwao River had turned blood-red on October 7, 2017.
According to witnesses, the colorless water was running normally until at 5am when it suddenly turned blood red within minutes.
The mysterious phenomenon baffled local residents and drew a crowd of curious people to experience this absolutely incredible event with their own eyes.
Local residents believe butchers have poured a large quantity of blood from animals slaughtered in the river. The regional police however believes the blood red color of the river is due to pollution – but there are no factories in the area – or to a mystery. What about this mystery being algae?
Meanwhile officials are investigating the cause behind the red dyeing of the Nsukwao River.
