A media tycoon in Cameroon has been arrested in connection with the killing of the prominent radio journalist, Martinez Zogo.

The businessman Jean-Pierre Amougou Belinga, the owner of L’Anecdote media group, was arrested just before dawn.

Zogo was abducted three weeks ago outside a police station in Yaoundé. His body was found heavily mutilated five days later.

The authorities announced last week that they had made several arrests in connection with the killing.

Three years ago another Cameroonian journalist, Samuel Wazizi, disappeared then died in state detention and an investigation into his death was not made public.
