One of Sierra Leone’s most prominent broadcast journalists has been detained after criticizing President Ernest Bai Koroma’s handling of the Ebola crisis, leading to public outcry amongst journalists and other free speech advocates in the country.

Radio host David Tam Baryoh, who hosts a weekly program called “Monologue,” was interrupted in the middle of his broadcast on Saturday following his interview of an opposition party spokesman who was criticizing the president, according to listeners of his show. A senior police official in Sierra Leone reported that Tam-Baryoh was arrested by “an executive order signed by his excellency the president,” and that his detention would remain in effect “until it pleases his excellency” to release him.

Concerns have been raised regarding not only Tam-Baryoh’s violation of rights by being detained, but also his health, safety and welfare while he is held in maximum-security prison. Tam-Baryoh has reportedly been experiencing health problems such as chest pain, and his wife is currently barred from visiting him.

Tam-Baryoh’s offices were raided by police, who took his computer and CDs, “causing panic in the office,” BBC and Freetown Politico reporter Umaru Fofana tweeted on Thursday.

Peter Nkanga, a West Africa Representative of the Committee to Protect Journalists, has called upon the President Ernest Bai Koroma to release Mr. Tam-Baryoh immediately. “Sierra Leone’s genuine state of emergency means that critical thinking and public debate are more important than ever,” he said in a statement. “Locking away journalists without charge helps nobody.”
