The government of Kenya has switched back giant televisions NTV and KTN News seven days after switching off transmissions.
However, Royal Media Services Citizen TV remains shut with no immediate explanation given by the state.
For a week now, civil rights activists and opposition politicians have accused the government of infringing access to information.
According to Interior Cabinet Secretary Fred Matiang'i, the affected media houses violated intelligence information on security threats during purported Raila Odinga inauguration.
"We are investigating media houses for violating intelligence briefs. The law shall be taken if any is found guilty," he said.
Last week, the US and EU condemned switching off of the leading television stations, arguing that it violates basic human rights.
"The US is concerned about switching TVs off since it violates basic human rights. We demand that they are reinstated."
Citizen TV, which remains off for sometime now, is owned by business mogul S.K Macharia, who once supported Raila's presidential bid.
