President Uhuru Kenyatta has cast his vote at the Mutomo Primary School.
Uhuru arrived at 9 am and began looking for his name in the register before he could cast his vote.
Accompanied by tight security, Uhuru could be seen casting his vote as journalists took pictures of him.
Uhuru was accompanied by his wife and other friends.
A contingent of GSU officers had arrived earlier at the polling station.
The GSU officers were seen walking into the polling station before his arrival at the polling station.
Voters started to cast their ballots shortly after the official opening of the polls at 6 am.
Uhuru is stepping down from power after the end of his two-term limit.
The main candidates vying to replace him are far from fresh faces.
William Ruto, 55, has been Uhuru's deputy for the past 10 years, though they have fallen out, with both pointing fingers at each other.
