Unknown assailants have shot dead an investigative journalist from Ghana after he uncovered corruption in Ghana’s football leagues.

Ahmed Hussein-Suale was shot twice in the chest and once in the neck in the an Accra suburb on Wednesday while he was heading home.

His work with journalist Anas Aremayaw Anas, as part of the Tiger Eye Private Investigations organisation, uncovered a massive corruption scandal in Ghana professional football, eventually leading to the lifetime ban for the former head of Ghana’s Football Association.

Following that investigation, a Ghanaian MP Kennedy Agyapong called for retribution against Hussein-Suale.

Ghana’s President Nana Akufo-Addo said he expects the police to find those responsible for the murder.

Ghana is generally considered a safe country for journalists. According to the Committee to Protect Journalists, one journalist has been killed in the country since 1992.

That murder took place in 2015, when radio reporter George Abanga was shot dead allegedly for his reporting on a dispute among cocoa farmers and regional political tensions.
