A cloud of political uncertainty is hovering around the nook and crannies of Kenya.

Opposition leader, Raila Odinga held a swearing-in ceremony in Nairobi on Tuesday in front of thousands of supporters in another challenge to President Uhuru Kenyatta's re-election last year.

Kenya's interior minister, however said Odinga's mock inauguration as "people's president" was an effort to overthrow the government and media outlets were shut down for their complicity in the event.

The lawyer and MP who swore Odinga in, TJ Kajwang, was arrested on Wednesday afternoon and is being investigated for his role in the ceremony, according to a senior police officer speaking on condition of anonymity.

After initially vowing to block the gathering, police kept their distance, but there was an outburst after the Communication Authority shut down three of the country's main private television channels who were covering the ceremony.

"What was witnessed at Uhuru Park was a well-choreographed attempt to subvert or overthrow the legally-constituted government of the Republic of Kenya," Interior Minister Fred Matiangi said in a statement.

"Some elements in the media fraternity participated in furtherance of this illegal act," he charged.

The shutdown came after media organisations were summoned to State House last week for a meeting.
