Senate Majority Leader Kipchumba Murkomen on Sunday asked President Uhuru Kenyatta to consider visiting Mau forest to establish the controversy.
The government of currently evicting people from the region, a move that has irked a section of Rift Valley leaders who accuse the government of irresponsiveness.
And Murkomen said Environment CS Keriako Tobiko was running a kind of concentration camp in Narok South with the help of Regional Coordinator George Natembeya.
The Elgeyo-Marakwet senator vowed to continue fighting for the rights of people, accusing the two of allegedly torturing the people of Mau.
"I want to urge the president. Please come and help these people. Tobiko and his team are running a concentration camp where they torturing them," he said.
"Those who believe I should not talk are misguided. Let us help the government in the morning and in the afternoon, I will not hesitate to correct the same people working for government," he added.
President Uhuru Kenyatta has remained mum about the Mau Forest eviction saga, with his deputy William Ruto also keeping bay.
Mr Natembeya said residents of Sierra Leone are cooperative but those in Kipchoge, Kitoben and Kass FM are trying to resist.
"You cannot resist and we have allowed you time to leave peacefully," said Natembeya.
Top government officials could be arrested soon for allegedly grabbing the Mau Forest land even as the evictees continue to push for compensation.
