The former Harambee Stars defender and coach handed in his resignation letter on Friday which was later accepted by the club.
“We received his letter of leaving the club on Friday, June 7, and we accepted his decision,” Gor Mahia chairman Ambrose Rachier told Goal.
“As Gor Mahia we would like to wish him all the best for the coming future and also thank him for what he offered this great club during his time here “
The source privy to the move told Goal, “Otieno is going to take charge at KCB from the new season because the Bankers have fired Ouna. He has agreed all the contractual terms and that is the reason why he resigned from Gor Mahia.”
After the end of the 2012 KPL season, Otieno left Sony Sugar to become a politician. He ran for the post of Councillor of Eastlands, Nairobi during the 2013 general elections, but took a break and was re-appointed at Sony Sugar.
