Speaking at Harambee House during a press conference, Mr Matiang'i divulged that they had launched investigations against members of the Fourth Estate allegedly working with the National Super Alliance (NASA) to cause mayhem during the swearing-in of Raila Odinga as People's President.
"The Government was and is aware of the role of some elements in the media fraternity who participated in furtherance of this illegal act.
"Their complicity would have led to thousands of deaths of innocent Kenyans due to the buildup of the incitement that was witnessed in early hours of the morning of 30 January 2018,” he said.
On Tuesday, the Government shut down KTN, KTN News, NTV and Citizen TV's on both the free-to-air and paid platforms in a bid to restrict the swearing-in ceremony of Mr Odinga.
During the briefing, Mr Matiang'i also explained why police officers were withdrawn from Uhuru Park noting that they had intelligence of some criminal gangs planning to conduct a massacre in the City.
According to the minister, armed goons were transported from different parts of the country to the Capital to conduct illegal activites.
He noted that to subvert this, he decided to withdraw the security officers.
