Journalists will on Monday protest in a show of solidarity with Nation Media journalist Walter Menya who was arrested on Sunday.
The protest organised by Kenya Union of Journalists (KUJ) will begin outside Nation Centre, Nairobi.
KUJ Secretary General Eric Oduor, arguing that Menya was set up, said journalists must say no to intimidation.
"All journalists must come out to say no to intimidation and show solidarity with Walter Menya who was arrested after a setup."
Nation said Menya was arrested following a story he penned in the company's Sunday newspaper.
In a statement, the media house protested intimidation of journalists following the treatment of its writer.
"We are seeking facts from the investigating authorities to enable us take appropriate action," Clifford Machoka, head of corporate affairs, said.
Police spokesman George Kinoti, in a statement, said Menya is accused of soliciting money to kill the said story.
He said the journalist will be taken to court but did not specify the charges.
However, the police are yet to reveal the complainant in the case.
Kenyans took to social media where they condemned the arrest and intimidation of media workers.
Lawyer Donald Korir said via twitter: "It's truly sad when paid bloggers accuse Walter Menya of extortion before he is convicted. Our Constitution is explicit on innocence."
Odeo Sirari of the BBC said: "If it is true, whoever was 'bribing' Menya must also be arrested. The law says, both the receiver & the giver are guilty."
Nelson Havi, also a lawyer, said: "What has Walter Menya done to be handcuffed as though he stole maize or SGR tickets? We stand with him against the merchants of fake news."
State House director of digital Dennis Itumbi said: "Walter Menya is a great journalist. He writes well and researches his stories. The court gives him a chance to defend himself."
