A vehicle in President William Ruto's motorcade is reported to have run over a man, killing him instantly.

According to an eyewitness account, the elderly man - said to be a foreign national -  was crossing the busy Ngong Road at the Greenhouse Mall, near Adams Arcade, when a loud thud was heard.

The said vehicle, however, sped off, joining the rest of the motorcade as it made its way into Kibra for scheduled presidential functions.

The incident followed other presidential development engagements in the neighbouring Lang'ata area as the President continued his tour of Nairobi.
