Ms Odinga and Senator Fred Outa reportedly went missing on Wednesday shortly after disrupting an IEBC officials training.
Kisumu County Chief of Staff Patrick Ouya said that the two leaders had been arrested and taken to an unknown police station.
Refuting the claims was Nyanza regional police boss Leonard Katana who said they (police) were yet to make any arrests.
Odinga while speaking in Bondo preached peace. He asked his people not to attack the Kikuyu but live together in harmony.
“Do not attack innocent people. That Kikuyu businessman here in Bondo is innocent. They have nothing to with what we are facing today. Please…please…please…please. No one, no Kikuyu, should be punished for the sins of Uhuru. If God punishes him, it will be him alone,” Odinga said.
President Uhuru Kenyatta warned the former Prime Minister against trying to stop the October elections.
