Shocking details have emerged on the last minute arrest of a man who managed to sneak to the venue of a presidential function while carrying a bullet.

President Uhuru Kenyatta and Deputy President William Ruto had on Saturday attended a thanksgiving prayer rally at Afraha Annex Stadium on Saturday after charges against the latter were terminated at the International Criminal Court (ICC).

Detectives arrested 21 year-old Mr Dickson Oduor Gwala at the venue of the rally with one round of 7.62mm.

The Nairobi News understands that detectives thereafter went with the man to his Bondeni residence to conduct a search. The findings of the search have not been released.

Details are not clear on how far the man was arrested from the main dais where President Kenyatta, William Ruto and other high ranking state officials were seated.

Police have also not released information on whether the man was a lone ranger or part of a network.

The man is being held at a police cell in Nakuru as police continue with investigations.

About 4,000 police officers, some from the neighbouring counties of Baringo, Narok and Nyandarua, were deployed at the venue of the rally, to pat down everybody going into the venue and verify their identities.
